PHOTOCHEMISTRY OF N-ACYLAZOLES. VI). PHOTOREACTIVITIES OF 1-ACYL-1,2,4-TRIAZOLES AND OF 2-ACYLTETRAZOLES

Article abstract of DOI:10.1002/hlca.19800630306

Contrary to the findings in the photolysis of N-acylimidazoles (2) irradiation of 1-acyl-1,2,4-triazoles afforded no photo-Fries product, but instead products formed via the corresponding acyl radicals and aldehydes.Photolysis of 2-acyltetrazoles gave in part the same products as those obtained from the irradiation of the corresponding acyl-triazoles as well as 2-alkyl-1,3,4-oxadiazoles.N-Acyltetrazoles didn't give any photo-Fries product neither.
