Dipole moments and conformation of some 1-(α-aroyloxyarylideneamino)-4,5-dimethyl-1,2,3, triazoles

Abstract

The dipole moments of four 1-(α-aroxyloxyarylideneamino)-4,5-dimethyl-1,2,3-triazoles were measured in benzene solution. The probable conformation of these compounds was determined after a theoretical calculation of the dipole moments by vector addition of the moments of all polar groups, It was found that the Zisomer is present and the probable conformation of the ester-imino-function is similar to that of acid anhydrides and other related compounds. The conformation of the molecule in solution is in general very similar to that found in the solid state by X-ray measurements.
