摘要：

The homocoupling of various organolithium and -magnesium compounds was' effectively induced by oxidation with oxovanadium(V) compounds under mild conditions, affording the diynes and biaryls selectively. The oxidation capability of oxovanadium(V) compounds depends an their substituents, giving the reactivity order, VO(OR)Cl-2 > VO(OR)(2)Cl > VO(OR)(3). The reaction path was investigated by V-51 NMR.
