A simple cobalt complex, such as Co(phen)Cl₂, turned out to be a highly efficient and cheap precatalyst for a host of cross-coupling reactions involving aromatic and aliphatic organoaluminum reagents with aryl, heteroaryl and alkyl bromides. New C(sp²)–C(sp²) and C(sp²)–C(sp³) bonds were formed in good to excellent yields and with high chemoselectivity, under mild reaction conditions.

钴催化芳基和烷基铝衍生物与（杂）芳基和烷基溴化物的交叉偶联反应

简单的钴配合物，如 Co( phen )Cl ₂，被证明是一种高效且廉价的预催化剂，可用于许多交叉偶联反应，包括芳香族和脂肪族有机铝试剂与芳基、杂芳基和烷基溴化物。在温和的反应条件下，新的 C(sp ² )–C(sp ² ) 和 C(sp ² )–C(sp ³ ) 键以良好到极好的产率和高化学选择性形成。
