Abstract
Irradiation of 2,5-diphenyl-1,3,4-oxadiazole in alcohols induces a heterolytic addition of alcohols to the C=N bond of the oxadiazole, followed by cycloelimination to yield benzoic acid ester and benzonitrile imine. The latter reacts with the oxadiazole to form 4-benzamido-3,5-diphenyl-1,2,4-triazole which is photochemically transformed into benzamide and 3,5-diphenyl-1,2,4-triazole. Upon irradiation of 2-phenyl-1,3,4-oxadiazole in methyl alcohol, the 1:1 adduct is obtained.
