A new synthetic method for 1-aryl-2-alkenes from 1-olefins by benzylation treating with benzyl trifluoroacetates using palladium-catalyst is developed on the basis of oxidative addition of benzyl carboxylates to Pd(0) complexes to give benzyl(carboxylato)palladium(II) complexes with cleavage of benzyl–oxygen bond.
在苄基
羧酸盐与
钯(0)络合物氧化加成的基础上,利用
钯催化剂通过
三氟乙酸苄基酯进行苄基化处理,生成苄基(羧基)
钯(II)络合物,并裂解苄基氧键,从而开发出一种从 1-烯烃通过苄基化处理合成 1-芳基-2-烯烃的新方法。
