Abstract

Reactions of 1, 4-dilithiobutadienes (from 1, 4-diiodo-1, 2, 3, 4-tetraethylbutadiene (1) and 2, 2′-dibromobiphenyl (7) with t-BuLi) with Me3SiCl gave siloles (3 and 9a) as the major products. No evidence for a disilylated butadiene was obtained. Use of higher molecular weight chlorosilanes ((allyl) Me2SiCl, BnMe2SiCl, and PhMe2SiCl) with dibromide 7 gave dimethylsilole 9a and a silane (10a, 10b, or 10c) resulting from trapping of the organic ...
