TITLE: Vibration Prequencles of Si - H and St - D Bondsland
Electronegativity of Silyl. Groups
PERIODICAL: Izvestiya Akademil nauk SSSR. Otdoleniye kh1micheakikh nauk,
1960, No. 6, pp. 1133-1135
TEXT: In a number of previous papers (Refs. I - 4) the authors have
already established the dependence of the vibration frequencies of the
S1 - H and Si - D bonds on the nature of atoms and groups bound to
silicon. There is no precise relationship between the vibration
frequencies of Si - H bonds and the sum of ele3tronegatirities. Better
results are obtained by making use of electronegativities of groups,
determined from the vibration frequencies (Ref. 6). However, as may be
seen from Table 1, the empirical relation developed also holds for
silicon hydrides. If the data obtained are recorded in a diagram, a
straight line is obtained, whose equation reads: H - 1011.X c (1).

Vibration Frequencies of Si - H and Si - D S/062/60/000/006/022/025/XX
Bonds and Elec.tronegativity of Silyl Groupa B02O/BO6O
This equation serves for calculating the mean values of the
elec-tronegativities of the silyl groups on the basis of thq values
indicated in Table 1. The same equation can also be -ised to calculate the
vibration frequencies of Si - H bonds in otbe.r ei.licon hydrides, Jxf the
electronegativities of the silyl groups are known. The "effective',
electronegativity of an arbitrary silyl group oontaining given atoms or
organic groups can be determined from the data indicated in the Table?
and hence, the desired vibration frequency of the Si. - H bond by
substituting into equation (1). This is clearly indicated by the data
given -4n Table 2. For silicon deuterides the equation reads:
-j Si - D ' 734.xc . For hydrides and deuterides of germanium the same
relation holds on principle, the coefficienta only being different.
There are 2 tables and 10 references: 5 Soviet, 3 Us, I British,, and
1 French.

TEXT: In previous papers the author found that alkyl- and alkenyl
radicals, bound to the silicon atom, exert only little mutual influence
(Refs. 1-3). The Si atom prevents interaction, The relation between the
structure of the radical and the frequency of the symmetrical Yi.bration
V(Si - C) is discussed here. On the basis of a comparison of the published
data with his results, the author arrives at the conclusion that the sym-
metrical frequency v(Si - C) covers the range 500-700 cm-1. This frequency
can be easily identified in the spectrum since it in intensive and
polarized. The form of the normal vibration, corresponding to the given
frequency,is linked with the maximum change of the polarizability

change of all Si - C bonds. The substitution of a radical for a radical of
different structure causes a new distribution of the electron density on
the shellof the Si atom, which~ in turn, affects the frequency of the
Symmetrical vibration, It was experimentally confirmed tYat the stronger
eleetronogativo radicals increaso the frequency V(Si - C), the weaker
electronegative ones reduce it. Fig, I ahowa tho dnpondanco of the rarlIcal

effect upon the electron shell of the Si atom, cauning a change of the

TITLE: Addition of Silanes, to Alkenylbenzenes in the Presence
of Chloroplatinic Acid
PERIODICAL: Zhurnal obshchey khImil, 1950, Vol 30, Nr 2, PP 376-
383 (USSR)
ABSTRAM The authors effect-W addition of trichlorosilane and
alkyldichlorosilanes to styrene, allylbenzene, and Y
butenylbenzene by L13irig chloroplatinic acid as a
catalyst (I ml of 0.1 M solution In isopropyl alcohol'
per 1.2 mole each of 311ane and allcenylbenzene. The
reaction was performed at 30-400, in a four-neck round-
bottom flask, provided with a stirrer, reflux condenser,
thermometer, and a dropping funnel (for olow and con-
tinuous addition of the alkenylbenzenc,). While addi-
tion of trichlorosilane results in only one product,
the methyl- and ethyldichlorosilaties produce two isomers
