Treatment of aryl chlorides with catalytic amounts of (PPh3)2NiCl2+PPh3 in the presence of an equivalent of Me2NH·BH3 and either K2CO3 or Cs2CO3 in CH3CN under mild conditions leads to the corresponding product of reduction. Aryl bromides and iodides can also be reduced, selectively, using this reagent combination.
在温和的条件下,在CH 3 CN中当量Me 2 NH·BH 3和K 2 CO 3或Cs 2 CO 3的存在下,用催化量的(PPh 3)2 NiCl 2 + PPh 3处理芳基氯化物导致减少到相应的乘积。使用这种试剂组合,也可以选择性地还原芳基溴化物和碘化物。
