The reaction of α-diazocarbonyl compounds with 1,1-diphenylmethanimine in the presence of Cu(acac)2 afforded the corresponding N-substituted imines in general together with pyrrolidine and 1,4,6-dioxazocine derivatives (in the reaction of α diazo-4-chloroacetophenone) and 1,1-diphenyl-2-(4-nitrobenzoyl) ethylene (in the reaction of α-diazo-4-nitroacetophenone) through azomethine ylides.
α-重氮羰基化合物与1,1-二苯基甲烯胺在Cu(acac)₂存在下反应,通常获得相应的N-取代亚胺,同时产生吡咯烷和1,4,6-二噁唑啉衍生物(在α-重氮-4-氯乙酰苯酮的反应中)以及1,1-二苯基-2-(4-硝基苯甲酰)乙烯(在α-重氮-4-硝基乙酰苯酮的反应中),通过亚胺亚基。
