PHOTOLYSIS OF 1,3,4-OXADIAZOLES IN ALCOHOLS [PDF]

Chemistry Letters, 1977
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 ...
