| 摘 要： | 根据在两价钯催化的亲核试剂－炔烃－α,β-不饱和羰基化合物的串联加成反应中所假设的烯醇钯中间体的机理，研究了炔酸烯丙酯化合物1和亲电试剂在两价钯催化下的反应。使用乙酰氮作为亲电试剂得到了β－乙酰氧基烯基－γ－丁丙酯3，这一结果为烯醇钯中间体的机理提供了一个实验证据。

| Abstract: | According to the mechanism involving pallium enolate intermediate in divalent palladium catalyzed nucleophile-alkyne- α,β-unsaturated carbonly tandem additions, the reactions of the enyne ester 1 with electrophiles under the catalysis of divalent palladium were examined. Employing acetyl chloride as the electrophile afforded the β-acetoxyvinyl-γ-butyrolactone 3 as the product, which provided an experimental evidence to the mechanism involving the palladium enolate intermediate. |
