Abstract

Thermolyses of disupersilylsilanes R* 2SiX2 (R*= supersilyl= SitBu3; X= H, Hal or H together with Me, Ph, Br) at about 160° C lead—besides R* X (R* H preferred to R* Br)—to silylenes R* XSi (X= H, Me, Ph, Br), the intermediate existence of which is proven by trapping them with Et3SiH (formation of Et3Si–(R* XSi)–H), with I2 (formation of I–(R* XSi)–I) or with CH2 CH–CH CH2 (formation of [1+ 4] cycloadducts). The rate of R* X ...
