Reaction of diphenyldiazomethane with N-methyloxy- and N- ethyloxycarbonyl-N-(2,2,2-trichloroethylidene)amines

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.

1,3-Dipolar cycloaddition of diaryldiazomethanes across N -ethoxy-carbonyl- N -(2,2,2-trichloroethylidene)amine and reactivity of the resulting 2-azabutadienes towards thiolates and cyclic amides

1,3-dipolar cycloaddition of diaryldiazomethanes Ar2CN2 across Cl3C-CHN-CO2Et 1 yields Δ3-1,2,4-triazolines 2. Thermolysis of 2 leads, via transient azomethine ylides 3, to diaryldichloroazabutadienes
