Palladium(II) complexes, such as (CH3CN)2PdCl2 and (diene)PdCl2, catalyze 1,3-alkyl migration of 1-alkenyl ethyl acetals and subsequent elimination of ethanol to give α-alkylated (E)-α,β-unsaturated carbonyl compounds in excellent yields.
钯(II)配合物,如(CH3CN)2PdCl2和(二烯)PdCl2,能催化1-烯基
乙缩醛的1,3-烷基迁移反应,随后脱去
乙醇,以优异的产率生成α-烷基化的(E)-α,β-不饱和羰基化合物。
