What is Tetraphenylsilane?
Chemical properties
White solid. Very stable and inert. Combustible.
The Uses of Tetraphenylsilane
Heat-transfer medium, polymers.
Preparation
Tetraphenylsilane (TPSi) can be obtained by reaction of phenylmagnesium bromide
with tetrachlorosilane or by reaction of phenyllithium with alkoxysilanes.
Purification Methods
It crystallises from *benzene as clear colorless bladed needles. It decomposes at ~360o/~760mm on attempted distillation. [George et al. J Am Chem Soc 77 6647 1955, Polis Chem Ber 98 1540 1885, Drew & Landuist J Chem Soc 1480 1935,s Beilstein 16 H 901, 16 I 525, 16 II 606, 16 III 1199, 16 IV 1372.]
