Herein, we describe an electroreductive cross-electrophile coupling protocol for the construction of valuable monofluoroalkenes from easily accessible alkyl or alkenyl halides with gem-difluoroalkenes. The reaction can be conducted under sustainable and mild conditions delivering valuable and functionalized monofluoroalkenes with excellent Z-selectivity. The protocol’s most notable advantage is the in situ release of nickel catalyst from the inexpensive electrodes without the addition of extra hazardous metal catalyst and superstoichiometric reductant.

烷基或烯基卤化物与偕二氟烯烃的电化学还原交叉偶联

在此，我们描述了一种电还原交叉亲电子偶联方案，用于从易于接近的烷基或烯基卤化物与偕二氟烯烃构建有价值的单氟烯烃。该反应可以在可持续且温和的条件下进行，产生具有优异Z选择性的有价值的官能化单氟烯烃。该协议最显着的优点是从廉价电极中原位释放镍催化剂，无需添加额外的危险金属催化剂和超化学计量还原剂。
