Branched tetrasilane substituted phosphines – synthesis and characterisation of PhSi(SiiPr2)3P and {PhSi(SiMe2)3}2P14†
Abstract
The branched trichlorotetrasilane PhSi(SiMe2Cl)3 reacts with P7(SiMe3)3 leading to formation of a new oligophosphane {PhSi(SiMe2)3}2P14 (1), which consists of two PhSi(SiMe2)3 substituted P7 norbornane units. The phosphatetrasila[1.1.1]pentane derivative PhSi(SiiPr2)3P (3) was obtained from the reaction of PhSi(SiiPr2Cl)3 (2) with Li3P.
