Reaction of the title imines with diphenyldiazomethane gives a Δ3-1,3,4-triazoline, which leads, after loss of dinitrogen, to a transient azomethine ylide. Subsequent elimination of ethyl or methyl chloroformate gives the unexpected 1,1-diphenyl-4,4-dichloro-2-aza-1,3-butadiene.
标题亚胺与二苯基重氮甲烷的反应得到 Δ3-1,3,4-三唑啉,在失去二氮后,它会导致短暂的偶氮甲碱叶立德。随后消除氯甲酸乙酯或氯甲酸甲酯得到意外的 1,1-二苯基-4,4-二氯-2-氮杂-1,3-丁二烯。
