  An alternative route to allylgermanes by the palladium-catalyzed reaction of germylsilanes with allylic halides

  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.

  (Triethylgermyl)tributylstannane reacts metal-selectively with allylic halides at room temperature (r.t.) in the presence of tris(dibenzylideneacetone)dipalladium, Pd2(dba)3CHCl3, to provide an alternative route to allylgermanes. (Dimethylphenylgermyl)tributylstannane regio- and stereoselectively reacts more readily with allylic halides than (triethylgermyl)tributylstannane affording the corresponding allylgermanes

  （三乙基锗基）三丁基锡烷在室温（rt）下在三（二亚苄基丙酮）二钯，Pd 2（dba）3 CHCl 3的存在下与金属烯丙基卤化物发生金属选择性反应，从而提供了另一种制备烯丙基锗烷的途径。与（三乙基锗基）三丁基锡烷相比，（二甲基苯基锗基）三丁基锡烷与烯丙基卤化物的区域和立体选择性反应更容易，以定量收率得到相应的烯丙基锗烷。
