A mild nickel‐catalyzed electrochemical approach for phosphonylation of aryl and vinyl bromides is reported. The used of iron/nickel alloy sacrificial anode process in undivided cell and under constant current electrolysis allowed to achieve C(sp2)–P cross‐couplings from alkyl H ‐phenylphosphinates and aryl or vinyl bromides. This electrochemical method enabled to prepare more than 30 new (hetero)aryl
报道了一种温和的镍催化电化学方法,用于芳基和乙烯基溴的膦酰基化。铁/镍合金牺牲阳极工艺在不间断的电解槽中并在恒流电解下使用,可以实现从H-苯基次膦酸烷基酯与芳基或乙烯基溴化物的C(sp 2)-P交叉偶联。这种电化学方法能够以良好的收率制备30多种新的(杂)芳基和乙烯基苯基次膦酸酯。
