Alkynyl(aryl)(diorganyl)borates, anionic tetrahedral boron compounds, reacted with allylic bromides in the presence of a palladium(0) catalyst to produce (diorganyl)(trisubstituted alkenyl)boranes. Allylation took place at the alkynyl carbon β to boron, inducing 1,2-migration of the aryl group on the anionic boron center to the α-carbon.
阴离子四面体硼化合物炔基(芳基)(二甘氨酰)硼酸盐在钯(0)催化剂存在下与烯丙基溴化物发生反应,生成(二甘氨酰)(三取代烯基)硼烷。烯丙基化作用发生在炔基碳 β 与硼之间,诱导阴离子硼中心上的芳基向 α 碳发生 1,2 迁移。
