Abstract
Oxidation of the title compounds yields O-acyl imidic acids derived from 1-amino-1,2,3-triazoles. This structure best explains the chemical and spectroscopic data and is confirmed by an X-ray crystallographic study of 1-(α-benzoyloxybenzylideneamino)-4,5-dimethyl-1,2,3-triazole (10). Crystals are monoclinic, space group P21/c with Z= 4 in a unit cell of dimensions: a= 5·94 ± 0·03, b= 10·76 ± 0·05, c= 27·31 ± 0·14 Å, β= 100·8°± 0·3°. The structure was solved by direct methods and refined to R 0·094.
