Irradiation of isonicotinohydrazide (Iγ) and its analogs (Iα and Iβ) in alcohols, i.e., methanol, ethanol, isopropyl alcohol, and benzyl alcohol afforded two types of photoproducts, that is, the alkylidenehydrazides (II, IV, VI) and the 2’-(2-hydroxyethyl)hydrazides (III, V, VII), except the cases of the hydrazides having ortho-amino and methoxyl groups which yielded the N-N bond fission products.
