Abstract
The preparation and lead tetraacetate oxidation of the mixed aroyl hydrazon es of biacetyl (2) to the pairs of isomeric 1-(alpha-aroyloxyarylideneamino )-3,5-dimethyl-1,2,3-triazoles (6) and (6') is described. The product ratio of 6/6' is evaluated in terms of the stability imparted to the zwiterionic intermediate (5) by the different substituents on the aroyl groups.
