ABSTRACT: It was shown already on an earlier occAsion~that acetoxilanes
react without any difficulties with al4hols to the
accompanim-~nt of the formation of corralidponding alkox;rsilanes
and acetic acid. In the course of the present paper the authors
investigated the possibility of applying this reaction to the
synthesis of cyclic ethers of dialkylsila-fteliols by the inter-
action of dialkyl(liacetoxysilanes withtelycols. A new met-hod of

ABSTRACT: In the previous paper of the authors,~:(Ref~l) the thermal addl-

this reaction to various diolefine hydrocarbons. There are

that a thermal and catalytic addition of the trichlo rosilene

were, however, not abl:e to add the:trichlorosilane to a serj!,'l
'
d6uble bonds in the
of diolefines vrhich contain conjugat'ed
presence of organic peroxides or unabr ult.raviolet irradiation,,
since a polymerization of the initial hydrocarbons took plac-3

peratures and under pressure. Thus the thermal addition of
the trichlorosilane to diolefine hydrocarbons with isolated
and conjugated double bonds was investigated. In the first
case the addition reaction takes a noTmal:course, according
t6 the rule of free radical addition. The'addition of the
trichlorosilane to 1,3 cyclopentadiene and dicyclopentediene
leads mainly to the formation of bis`(trichlorosilyl) cyclo-
pentane. The reaction of the triahlorosilane with 1,3-cYclo-
hexa~di4r*v, and above all with dipen tene, takes an abnormal
course, under formation of a product of the addition to the
corresponding oyclomono-olefine product of the "direct cata-
lytic transfo=ation" of the initial hydrocarbon. 6 additive
compounds of the trichlorosilane to,diolefines are described
the most of which were newly synthedizeC There are 2 t~ables
and 17 reforencest 12 of which are Soviet.

ABSTRACT: T'-~e organic derivatives of vanadium a-e little investi,vated,
especially, because vanadium is not liable to form stable
organic compounds with a vanadium-carb6n b9nd(Ref 1).
But also compounds in which a vanadium atom is combined
with a carbon by means of oxygen are deficiently
described (Ref 2). The present paper ;La an investilation of
the synthesis of hitherto unknown orgRnosilicon vanadium
derivatives which cont--in a binding,V-O-Si~( see the
title). The authors have produced these derivatives
by intcraction of triorganosilanes with V 90 5' VOC13
or aith trialkyl vanadates OV(OR) 3 as well.an the reaction
of the sodium triethyl ailanolate. The first method is
discussed. Another simple method of synthesis of tri-

trans-etherification of the trialkyll vanadatez, by means
of triorGanosilanolene in the presence of catalytic
amounts of sodium derivatives of the latters. They are
formed by addition of metallic sodium Finally, the
compounds in question can be produced~,vith'a good yield
by the reaction of sodium triorganosil,-wolates with

It~ follows from it that the alcohol need:praotically no-'.* take
part in the reaction and that dimethyl diethq,xy silare is formed
by the reaction of polydimethyl siloxanp. with tetraetho.Ty silane.
The experiments completely confirm thisAssimption. Thus the
simple distillation of the mixt,are of normal, branched, and
cyclic organosiloxane with tetr%- or organoalkoxy silane in the
presence of an alkaline catalyst (e.g. KOH) yields the
corresponding orgaiioalkoxy silane. This,-new and convenie=t
method is of preparative importance. Th,d reaction in the case of
Si(OR can be illustrated by scheme 5., where n-2-3 and m Oan

vary in wide limits. The dialkyl-dialko:xy- and trialkylalkoxy

saryq however? in order to obtain a great dep th of gluing.
If certain catalysts are usedy e.g. leadlor zi nc acetate,
triethanolamine, etop thermal prooeneing~~Is not nooessary,

Photochemical Chlorination of Organochlorosilanes by S,ulpharyl Chloride
Though the chlorination of methyl derivative,o in the medium of
a high-boiling solvent (Refs 70102)'fe successful, only a
small yield is obtained by it. The authors observed that an
ultraviolet irradiation catalyzes the last mentioned reaction
to a much greater extent than organic peroxides. Thus the use
of SO Cl for the chlorination under comparatively mild condi-

follows. An intensive irradiation of a~boili Ing mixture of methyl

TEXT: In their development of new methods of synthetilzing, silicon elemental-
organic compounds, the authors aimed at completing tht~ pravlous methods of
producing triorganosilyl esters of boric acid - tris(trio~rganoailyl)barate
by new methods. Three new methods were developed. They distinguish them-
selves from the older ones by high yields (80-95%). The first two are
based on the.reactions of triorganosilanoles with bbric anhydride or boric
acid: 3R3SiOR + B(OH) 3 (R.3Sio)3B + 3H20 (1)
6R SiOH + B 0 2(R Sio) B + 3H 0 (2)
3 2 3 3 3 !2
The third method of synthesis is based on the interaction between tri-
organosilanes and boric acid in the presence of colloidal ni-.kel:

The reactions (1) and (2) are based on an tininterrupf47~d azeotfopic
distilling off of water from the mixture of triorganon 1ilanples with boric
acid or with boric anhydride, containing an inert sol*ent (bonzone).
Tris(triorganosilyl)borate was produced according to'scheme. (3) by
heating mixtures of triorganosilane and boric acid inJtbe presence of
colloidal nickel, forming in the interaction of nickel chloride with
triorganosilane. 6 tris(triorganosilyl)borates were obtain Ie:d by the three
methods of synthesis. 4 of the compounds have hitherto, been unknown.

phosphorous acids belong to them. The authors have taken,the trouble to obtain
organophosphorus compounds which are, amongst other.thines, al~so anti-oxidants,

acids (I) and (II), or b) compounds in which phosphorus is bonded with oxygen
(III) and (IV) (Ref. 11). The authors have established that di :alkyl-p-oxy-

temperatures and the results of analyses of the compound ~produ~ced. They are

reaction for the carbonyl group. The hydrolysis of the au~ 13 tano~e~ obtained
with ECI (1s1), and the saponification with alcoholic alk6ilis at 40-500 gives a
yield of 8M,. All compounds produced contain only one hydioxyl':g-roup. On the
basis of the ultraviolet absorption spectra the authors have siated that esters
of p-oxyphenyl-phosphorous acid are concerned. As can be,tieen from table 2, the
absorption maximum of the products is shifted towards shoat walles, and agmes.

The authors assume that the high stability of wat6r-rdpellant or-.

of the reactive functional groups in the utilized 'i monomers and poly-

ing thermal treatment of the fibers but also at rbon temperature
(especially in the presence of a catalyst); in the la tte r case the:
reaction is much slower, This hypothesis was 6onfirmed by experi-
ments on model systems. A water-repallont# chemlOorbed layer is
formed on the cellulose fibers. The effect of the' orlhiltation of
the hydrocaxbon radicals of the organosilicon compaund'13t and of the
hydrophilic hydroxyl groups of cellulose on the hydrophobic proper-
ties of this layer are discussed. Hydrophobing of materials, cont-L
aining OH groups (including cellulose) by using~ ~olya:lkyl hydro-
siloxanes is stated to proceed effectively in the,aboence of oxygen
or oxidising agents. Salts of Zn, Cdo Hgj Co aud~;Ni (.-acetates or
chlorides) are satisfactory catalysts. OrganoalliconJpolymers
which do not contain reactive functional groups. and therefore can-
not combine chemically with cellulose do not give stable water-re-
pellant coatings on textile fibers. The reaction'of organosilicon.

The authore have also found that organosilicon hydrop~obing agents.
combine well with Cu-and Cr-salt8, forming stabled'; compounds which
are retained for long periods on the textile materials. In the dis-
