AZOMETHINE IMINES BASED ON 4-PHENYL-1,2,4-TRIAZOLINE-3,5-DIONE AND ARYL-SUBSTITUTED DIAZOMETHANES

Stable azomethine imines were obtained from aryl-substituted aliphatic diazo compounds and 4-phenyl-1,2,4-triazoline-3,5-dione.Their properties and their cycloaddition to dimethyl acetylenedicarboxylate, in particular, were investigated.
