烯基(芳基)(二有机)硼酸酯是一种阴离子四面体硼化合物，在钯(0)催化剂的存在下与烯丙基溴化物反应生成(二有机基)(三取代烯基)硼烷。烯丙基化反应发生在烯丙基碳β上，导致阴离子硼中心上的1，2-芳基迁移到α-碳上。
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 allcynyl carbon beta to boron, inducing 1,2-migration of the aryl group on the anionic boron center to the alpha-carbon.
