Reactions of 1,4-dilithiobutadieties (from 1,4-diiodo-1,2,3,4-tetraethylbutidiene (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 group by the chlorosilane.
