New 2,4,6-Triisopropylp henyl-Substituted Disilenes. (Reannouncement withNewAvailability Information)

摘要

In this paper we report the synthesis of E and Z isomers of the first silyl-substituted disilene, 1,2-bis(trimethylsilyl) -1,2-bis(2,4,6-triisop ropylphenyl)disilene (1), as well as the analogous tert-butyl compounds (E)-2 and (Z)-2. In addition, the synthesis of several heteroatom-substituted trisilanes, Is(X)Si(Me3Si)2, is reported, along with results of photolysis of these compounds.
