TITLF,: Stereochemistry of Simple Cyclohexane Derivatives
(Stereokhim-iya
prosteyshikh proizvodnykh tsiklogeksana)
PERIODICAL: Uspekhi Khimii, 1957, Vol 26, Nr 1, PP 3-44 (U.S.S.R.)
ABSTRACT: Numerous references are presented showing that, at a
normal temperature,
cyclohexane exists in a more symmetrical chair-like form in which
the
distance between the carbon atoms is 1.54 A and the valent. angles
remain
almost tetrahedral. In compounds with free rotation of C - C bonds
the
zigzag trans-orientation of the carbon atoms corresponds to minimum
poten-
tial energy. The greater stabilitv. of the chair-like form of
cyclohexane
was confirmed by calculating the distance between hydrogen atoms
(13).
The analogous condition of the bath-tub like cyclohexane molecule
indi-
cates that the minimum distance between the hydrogen atoms is only
1.83 R (8); therefore, such form is considered energetically less
favorable.
1hploying the principle of least deviation of valent angles it is
possible
to prepare two cyclohexene models "half-chair" and "half-tub" which
correspond to the chair- and tub-like forms of cyclohexane.
According
to thermodynamic calculation (25), the form of the half-chair is
more
Card 1/2 stable than the half-tub.

Stereochemistry of Simple Cyclohexane Derivatives
The energy difference of both forms is approximately only
one-half as
much as for cyclohexane and constitutes only 2.7 kcal/mol, The
concepts
of equatorial and axial bonds and their energy differences are
explained.
A study of models of monosubstituted cyclohexanes and
cyclohexenes showed
their ring system to be rigid without experiencing any thermal
oscilla-
tions of atoms. None of the monosubstituted cyclohexane or
cyclohexene
derivatives was separated in form of stereoisomers, because the
axial and
equatorial forms are easily interchangeable. Cyclohexane
derivatives
possess a high inertness only during bimolecular substitution
reaction.
The inertness of cyclohexane derivatives is explained by the
steric
hindrances due to nonuniform structure of the ring. The
stereochemistry
of radical addition reactions of various cyclohexane derivatives
is
discussed.
Five tables; there are 238 references, of which 4 are Slavic.

ABSTRACTs
Recently it was demonstrated that ois-dibromo-vinyl
carbinols

(I) easily cleave off dehydrates and hydrogen
bromide while

forming unstable 1-bromo-vin acet enes (III).
When boiled
I

with alkali they produce' ot,~
- or ~,r-unsaturated acids

(Ref 1). In this paper a method of
producing unsaturated

acids is described which is based on
the mentioned reactions.

To increase the yield in substituted
dibromo butadienes (n)

*
dehydration of dibromo-vinyl carbinols (1) were investigated

under the action of heat and various dehydrating agents.

Optimum results were obtained in boiling with dibromo-vinyl

carbinols in petroleum ether with phosphoric anhydride (in

the case of cis-dibromo-vinyl dimethyl carbinol) or

p-toluene sulfo acid (in the case of cis-dibromo-vinyl
cyclohexanol). If-bromination of acetylene alcohols is
carried out in petroleum ether dehydration can take place
without separation of brominated alcohols (I). Substituted
dibromo butadienes (II) and especially vinyl acetylene
bromides (III) are unstable. They partly decompose and
saponify in the course of distillation. For this reason
it is expedient to carry out further processes of
dehydrobromination and of alkali hydrolysis in a single
stage without separation of bromine derivatives (II) and
(III). Under these conditions the transformation of acetylene
alcohols into unsaturated acids can be carried out in a great
number of cases in sufficient yield (Table 1). The constants
of all known acids agree well with -be data from publications.
There are 1 table and 15 references, I of which is Soviet.

addition (Refs 1 and 2). In carrying out this reaction in the
acetylene series we obtained completely different results. The
photochemical hydrobromination of methyl bromo acetylene M
and tert. butyl bromo acetylene (II) RC~_ CBr +
HBr--.PRCBr-CHBr
takes place stereospecifically and leads to products of the
cis-addition of hydrogen bromide, ioe. to the trans-dibromo
olefinB. The reaction was carried out under irradiation from
a mercury quartz lamp at -750 without solvent, or in pentane.
A similar hydrobromination of (II) led to the formation of
tert.

experiments it was

SOV/62-58-12-22/22
Radical Addition of Hydrogen Bromide to 1-Bromo Acetylenes
found that the cis-(III) does not isomerize during the
reaction.
For this reason the photochemical hydrobrom'nation of bromo
acetylenes represents a radical reaction of the cis-addition.

ABSTRACT: In the beginning it in mentioned that the initiul
attempf: of
a thermodynamic calculation of oroanic molecules by means of
statistical mechanics yielded satisfactory results only in the
case of rigid molecules. When the C-C bonds, however, are fz-
rotate these methods are not successful. After a further ex-
position of now findin,-,s in thin field the author deals with
the estimation of the relative stability of unbound substituents.
In a special section the problem of the binding of the con-
formity and of the transition state is discussed. The con-
ception of reaction conformity is explained; being that confor-
mity which approaches closest the transition state. The author
investigates next the separation reactions. In this section
the trans-separation is discussedlviz. bimolocular reactions

asweUas other reactions of trans-separation. Then the author
discusses the cis-separation. The investigation of the pro-
ducts discovered in the cleavage of xanthojenate (according
to Chugayev) showed that all these reactions take place
according to the scheme of cis-separation. In the pyrolyeis
of the erythro- and threo-2-deixtero-1,2-diphenyl ethanol-
acetates mainly 2 factors are effective: 1) The tendency of
the initial substances to react in a lees difficult confor-
mity, and 2) The Dtron6 tendency of deuterium to participate
in the process of separation. Finally the author discusses
the reactions of the substitution in a special chapter. There
are 3 tables and 71 references, 2 of whi;h are Soviet.

ABSTRACT: It is known that the catalytic hydrolgeriation
of acetylene'
compounds mainly leads to the cis-ethylenes (Reference
't)21
It was, however, noticed several times that besides these
also transasomers form; the quantities of which
apparently
depend on the nature of the acetylene com-pound', on the
catalyst and the hydrogenation conditions (Referen,-.es
2 .. 14), In ocnnec-'7-ion with the stereocheoii.~al

tions of the addition reactions to the triple bcnds car-
ried out by the authors it was of interest to determine

TEXT: Previous papers (Refs. 1,2) h3ve dealt with the
stereochemistry
of the bromination of monosubstituted acetylenes under different
conditions, The steric directivity of the reaction was found to
depend
on 4-+s mechanism: in ionic reactions the addition proceeds
chiefly
according to the trans-scheme, and in the photochemical

number of which
depends on the volume of the substituent R. The disubstituted
acetylenes:

(tetramethyl butynediol ), and acetylene di carboxylic acid,

described here. Cis-derivatives were obtained by the

butynediol diacetate yielded cis-dibromides, while tolan
yiellded chiefly
trans-additicn products, The steric directivity of the ionic
directicn was
studied by performing the brominaticti of butynediol and
tetramethyl

tetrahydrcfuranone-3 was
obtained in this process, Un'like acetylene glycols, acetylene

acid -
dibromo maleii acid mixture with a 75A trans-isomer content, As
contrasting with the mentioned aeetylenes. bulynediol is
brominated in

ABSTRACT:
The authors give a report on the
polarographic investigation

of cis- and trans-isomers of the
following compounds:

1-(11-oxycyolohex.vl)-1,2-dibromoethylene,
3-oxy-1,2-dibromo-3-

methylbutene-1, and
2,5-dioxy-3,4-dibromo-2,5-dimethylhexene.

The polarograms were
recorded in a 60% methanol solution at

250 and a background of
LiBr or (C 2 H5)4NBr according to a

method desoribed in
reference 2. The polarograms of all invesd-

gated substances
showed a single reduction stage with a diffu-

sion limiting
current. With a similar concentration of the

depolarizer the
waves of the cis- and trans-isomers have the

same height. The

TEXTS The poly-metallic ore from one of the Ural deposits was
tested for
concentration. In view of the fact that Zn, Pe, Cd (besides the
Au and Ag) may
be of some interest, the tests were carried out in the
direction of obtaining
methods of extracting the indicated elements. First the ore
under test was sub-
jected to gravitational concentration on a jigging machine and
a concentration
platform to separate out from the technological process the
unyielding ore and
the free Au and Ag. The gravitational concentrate was
sub-Jected to amalgamation,
and the residues of the amalgamation may be utilized as a
pyrite concentrate con-
taining up to 40% Fe and 50% S. The main technological process
of treatingthis
ore 45-urned out to be the collective flotation, to which the

ABSTRACT: This Author's Certificate introduces an arithmetic unit
for performing the
operations of addition and subtraction in self-checking cyclic
code. The device con-
tains flip-flop registers for the first and second numbers with
recording and set
1 circuits, a circuit for cyclic carry, determination of the
resultant sign and digital
network overflow check, and circuits for monitoring progress of the
operations. To
simplify the device and increase its speed, each i-th digital-place
except the flip-
flops of the registers for the first and second numbers contains
two modulo 2 adders,
a circuit for carry to the following i+1-th digit and a diode. The
direct (inverse)
outpu-~s of the flip-flops for the first and second numbers are
connected to the first
direct (inverse) inputs of the first and second adders
respectively. Connected to
the secona direct (inverse) inputs of the first and second adders
respectively are

NRs AP6025654
the direct (inverse) ouputs oi the first and second adders for
the preceding i-l-th
digit. The inputs of the carry circuit are connected to the
direct outputs of the
adders for the given circuit and to the carry output of the
preceding i-I-th digit
Vaich is also connected to the counter input of the flip-flop
for the first number of
the given i-th digit, and through the first delay line to the
counter input of the
flip-flop for the second number of the following i+l-th digit.
The direct outputs of
the adders for the most significant digit are connected to the
first inputs of the
first and second monitor circuits. The second inputs of these
monitor circuits are
comqected to the sign digits of the first and second numbers
reupectively. These
inputs are connected together with the-carry output for the
most significant digit
to the circuit for determination of the resultant sign,
overflow check-and cyclic
carry. The cyclic carry output of this circuit is connected
through the second and
third delay lines to the counter inputs of the flip-flops for
the first and second
digits of the second number and to the first input of the
firut collector circuit re-
spectively. The second input of this collector circuit is
connected to the control
signal source, while the output is connected to the inverse
inputs of the adders for
the most significant digit. The outputs of the second adder
are connected through
the second collector circuit and the fourth delay line to the
reset terminals of all
'lip
f -flops in the register for the second number and to the
first inputs of the di-
odes for all digits. connected to the second inputs of these
diodes are the direct
outpuzs'of the corresponding flip-flops in the register for
the second number. The
diode,outputs are connected to the counter inputs of the
corresponding flip-flops in
