✦ Synopsis

Abstract

Proton chemical shifts, as well as solvent shifts induced by benzene, can be used for the structure determination of 4,5‐asymmetrically substituted 1‐(N‐isoimido)‐1,2,3‐triazoles, derived from the oxidation of α‐diketone bisaroylhydrazones. The geometry of the postulated ‘collision complex’ is discussed and an attempt is made to estimate theoretically the induced shifts of some of the protons.

## Abstract The^13^C NMR spectra of some 1‐(__N__,__N__‐diaroyl)amino‐1,2,3‐triazole derivatives are reported. The shifts of the methyl carbons attached to the triazole ring and those of C‐4 and C‐5 of the ring were used to distinguish between 4,5‐unsymmetrically substituted derivatives. The locati
