介绍了钴催化的溴化有机锌的交叉偶联反应。在芳基锌试剂的情况下，相同的钴催化剂CoBr 2（phen）可用于有机锌物质的合成和交叉偶联反应。在烷基卤化锌的情况下，其允许获得二烷基炔，用于制备有机锌物质的方法对产率具有显著影响。
The cobalt-catalyzed cross-coupling of organozinc bromides is described. In the case of arylzinc reagents, the same cobalt catalyst, CoBr2 (phen), can be used for both the synthesis of the organozinc species and the cross-coupling reaction. In the case of alkylzinc halides, which allow access to dialkylalkynes, the method used for the preparation of the organozinc species has a significant impact on the yields.
