A direct and efficient method for constructing N,N-disubstituted hydrazines via a palladium-catalyzed allylic substitution of allyl acetates with arylhydrazines as nucleophiles has been developed. This method is highly selective in terms of both chemo- and regio-selectivity and is carried out under an open-air system with the use of the DPPPy phosphine ligand. Additionally, this reaction is compatible
已经开发出一种直接有效的方法,通过用芳基
肼作为亲核试剂对
乙酸烯丙酯进行
钯催化的烯丙基取代来构建N,N-二取代
肼。该方法在
化学选择性和区域选择性方面都具有高度选择性,并且使用
DPPPy 膦配体在露天系统下进行。此外,该反应与多种底物兼容,包括那些带有反应基团(如 Cl、Br 和 I)的底物,可在简单和温和的反应条件下以中等至良好的产率提供各种 N 1 -烯丙基化产物。
