Diazoalkylideneamine–1,2,3-triazole tautomerism in 1,2,3-triazolo[1,5-a]pyrimidines at elevated temperatures
Abstract
Simple examples of diazoalkylideneamine–1,2,3-triazole equilibria have been demonstrated for the first time in a fused system by variable temperature 1H n.m.r. studies of a series of 1,2,3-triazolo[1,5-a]pyrimidines.
