Oxidativeaddition of an aryl-halide to Ni(COD)2 in the presence of an equivalent of amino-bis-phosphinimine ligand affords complexes of the form [HN(CH2CH2NPPh3)2Ni-Ar][X] (Ar = C6H4F, C6H5, X = Cl, Br) while the analogous reactions with 2 equivalents of Ni yield the amido-bridged complexes N(CH2CH2NPPh3)Ni2Br3 and N(1,2-C6H4NPPh3)Ni2Br3.
在等效的氨基双-双膦亚胺配体存在下,将芳基卤化物氧化添加到Ni(COD)2中,得到[HN(CH 2 CH 2 N PPh 3)2 Ni-Ar] [X]形式的络合物(Ar = C 6 H 4 F,C 6 H 5,X = Cl,Br),而与2当量Ni的类似反应产生酰胺桥联的配合物N(CH 2 CH 2 N PPh 3)Ni 2 Br 3和N(1,2-C 6 H 4 N PPh 3)Ni2 Br 3。
