Various substituted and unsubstituted N-heteroaryl chlorides have been converted into their corresponding organozinc species using zinc dust in the presence of zinc pivalate and 10% CoCl2 in benzonitrile at 25 °C. The resulting heteroarylzinc reagents were obtained in 43–98% yield within 9–48 h and reacted with a broad range of electrophiles, leading to the functionalized heteroarenes.

钴催化相应杂芳基氯化物制备N-杂环有机锌试剂

在新戊酸锌和 10% CoCl2 的苄腈溶液中，在 25 °C 下，使用锌粉将各种取代和未取代的 N-杂芳基氯化物转化为相应的有机锌物质。得到的杂芳基锌试剂在 9-48 小时内以 43-98% 的产率获得，并与广泛的亲电子试剂反应，产生功能化的杂芳烃。
