An operationally simple iron-catalyzed hydrodehalogenation of aryl halides has been developed with 1 mol% Fe(acac)3 and commercial t-BuMgCl as reductant. The mild reaction conditions (THF, 0 °C, 1.5 h) effect rapid chemoselective dehalogenation of (hetero)aryl halides (I, Br, Cl) and tolerate F, Cl, OR, SR, CN, CO2R, and vinyl groups.
开发了一种操作简便的铁催化的芳基卤化物氢脱卤反应,使用1 mol%的Fe(acac)3和商业化的t-BuMgCl作为还原剂。温和的反应条件(THF溶剂,0°C,1.5小时)实现了(杂)芳基卤化物(碘、溴、氯)的快速化学选择性脱卤,并能耐受氟、氯、烷氧基、硫醚、氰基、羧酸酯和乙烯基等官能团。
