imines derived from N,N-dimethylethylenediamine, C6RnH5-nCH NCH2CH2NMe2 to [Ni(COD)2]. The molecular structure of [NiCl2-(CHNCH2CH2NMe2)-3-ClC6H3}] has been determined by a single-crystal X-ray crystallographic study. Some ionic compounds [Ni(C−N−N‘)L]BF4 (L = NCMe, heterocyclic amines) were also obtained. The NiC bond of these complexes is inert toward insertion reactions of ethylene or PhC⋮CPh. The action
