Cobalt(II)‐catalyzed C(sp2)O cross‐coupling between aryl/heteroaryl alcohols and vinyl/aryl halides in the presence of CuI has been achieved under ligand‐free conditions. In this reaction, copper plays a significant role in transmetalation rather than being directly involved in the CO coupling. This unique Co/Cu‐dual catalyst system provides an easy access to a library of aryl–vinyl, heteroaryl–styryl
钴(II) -催化的C(SP 2) Ô交叉耦合在Cu的存在之间的芳基/杂芳基醇和乙烯基/芳基卤化物我已被无配体的条件下实现。在该反应中,铜在过渡金属化中起着重要作用,而不是直接参与CO偶联。这种独特的钴/铜双催化剂系统可在没有任何配体或添加剂的情况下轻松访问芳基-乙烯基,杂芳基-苯乙烯基,芳基-芳基和杂芳基-杂芳基醚的库。
