摘要：

Pd(dba)(2) (bis(dibenzylideneacetone)palladium complex) effectively catalyzes the reaction of (dimethylphenylgermyl)trimethylsilane with 2-alkenyl halides to bring about metal-, regio- and stereoselective metathesis resulting in the formation of 2-alkenylphenylgermanes with good yields. On the other hand, the reaction of (chlorodimethylgermyl)trimethylsilane with 2-alkenyl halides is effected by a palladium-phosphine complex to give 2-alkenylchlorogermanes selectively. Germylation of 3,4-dichloro-1-butene with (dimethylphenylgermyl)trimethylsilane forms 1,4-bis(dimethylphenylgermyl)-2-butene with a high yield. (C) 1999 Elsevier Science S.A. All rights reserved.
