were coupled with phenylzinc bromides in Negishi cross-coupling reaction catalyzed by MeBICAAC-nickel complexes. The active species are deciphered by means of UV-vis, HRMS and NMR measurements and support the involvement of Ni(I)/Ni(III) species in the reaction promoted by [(MeBICAAC)2NiIICl2] pre-catalyst whereas, Ni(0)/Ni(II) cycle operates when the Ni(0) complex, [(MeBICAAC)2Ni0] was used as pre-catalyst
在Me BICAAC-镍配合物催化的 Negishi 交叉偶联反应中,多种芳基卤化物与溴化苯基锌发生偶联。活性物质通过 UV-vis、HRMS 和 NMR 测量进行破译,并支持 Ni(I)/Ni(III) 物质参与 [( Me BICAAC) 2 Ni II Cl 2 ] 预催化剂促进的反应而当Ni(0)配合物[( Me BICAAC) 2 Ni 0 ]用作预催化剂时,Ni(0)/Ni(II)循环运行。
