Branched tetrasilane substituted phosphines - synthesis and characterisation of PhSi(Si/Pr_2)_3P and {PhSi(SiMe_2)_3}_2P_(14)

摘要

The branched trichlorotetrasilane PhSi(SiMe_2Cl)_3 reacts with P_7(SiMe_3)_3 leading to formation of a new oligophosphane {PhSi(SiMe_2)_3}_2P_(14) (1), which consists of two PhSi(SiMe_2)_3 substituted P_7 norbornane units. The phosphatetrasila[1.1.1]pentane derivative PhSi(Si/Pr_2)_3P (3) was obtained from the reaction of PhSi(Si/Pr_2Ci)_3 (2) with Li_3P.
