Abstract

The photochemistry of some 1, 2, 4-oxadiazoles in the presence of sulphur nucleophiles has been investigated. Irradiation of the 5-amino-3-phenyl-and 3, 5-diphenyl-1, 2, 4-oxadiazole at γ= 254 nm in methanol in the presence of sodium hydrogen sulphide or thiols gave a photo-induced redox reaction at the ring O N bond, leading to the corresponding N- substituted benzamidines. By contrast, irradiation of the 5-amino-3-phenyl-1, 2, 4- ...
