A synthetic equivalent of parent azomethine imine is accessible by simple heating of ethyl 3-benzylcarbazate with paraformaldehyde under reflux in toluene in the presence of triethylamine, which effectively suppresses the undesired formation of imine dimers. The resulting imines can be trapped with a variety of dipolarophiles.
在三乙胺的存在下,通过在甲苯中回流下简单加热 3-苄基氨基甲酸乙酯和多聚甲醛,可以得到母体偶氮甲碱亚胺的合成等价物,这有效地抑制了不需要的亚胺二聚体的形成。产生的亚胺可以被各种偶极体捕获。
