alkenylborane and allylstannane units. A copper complex has been found to catalyze the borylstannylation of alkenes through three-component coupling with a diboron and a tin alkoxide, affording vic-borylstannylalkanes of structural diversity in a regio- and stereoselective manner. The versatility of this borylstannylation has been also demonstrated by employing allenes, leading to the sole formation of
摘要 一种铜络合物,已经发现通过与二硼和锡醇盐的三组分偶联催化烯烃的borylstannylation,得到VIC在一个区域选择性和立体选择性的方式的结构多样性的-borylstannylalkanes。硼烷基锡烷基化反应的多功能性也已通过使用丙二烯得到证实,导致仅形成具有烯基硼烷和烯丙基锡烷单元的硼烷基锡烷基化产物。 一种铜络合物,已经发现通过与二硼和锡醇盐的三组分偶联催化烯烃的borylstannylation,得到VIC在一个区域选择性和立体选择性的方式的结构多样性的-borylstannylalkanes。硼烷基锡烷基化反应的多功能性也已通过使用丙二烯得到证实,导致仅形成具有烯基硼烷和烯丙基锡烷单元的硼烷基锡烷基化产物。
