A new route for the direct cross-coupling of alkyl and allylic halides using electrochemical technique has been developed in aqueous media under air. Catalyzed by Pd(OAc)2, the Zn-mediated allylic alkylations proceed smoothly between a full range of alkyl halides (primary, secondary, and tertiary) and substituted allylic halides. Protection–deprotection of acidic hydrogen in the substrates is avoided
在空气中的水性介质中,已经开发出了一种使用电化学技术直接交叉偶联烷基卤化物和烯丙基卤化物的新途径。在Pd(OAc)2的催化下,Zn介导的烯丙基烷基化反应在各种烷基卤化物(伯,仲和叔)和取代的烯丙基卤化物之间平稳进行。避免了底物中酸性氢的保护-去保护。
