The reductive Barbier coupling of aromatic halides and electrophiles has been achieved using a CoBr2/1,10‐phenanthroline catalytic system and over stoichiometric amounts of zinc. The reaction displayed a broad scope of substrates, including (hetero)aryl chlorides as pro‐nucleophiles and aldehydes or imines as electrophiles, leading to diarylmethanols and diarylmethylamines in moderate to excellent
使用CoBr 2 / 1,10-菲咯啉催化体系和超过化学计量的锌可以实现芳香族卤化物和亲电试剂的还原Barbier偶联。该反应显示出广泛的底物范围,包括(杂)芳基氯化物作为亲核试剂和醛或亚胺类作为亲电试剂,分别导致了中等至极好的收率的二芳基甲醇和二芳基甲胺。
