Abstract

Abstract: By means of ESR method,the photochemical reactions of three acridine N-oxides with a series of hydrocarbons,alcohols,aldehydes and ketones have been investigated.Results show that acridine N-oxides posses strong ability of photochemical hydrogen-abstraction; the nitroxyl iree radicals formed in H-abstraction reaction are rather stable,the lifetime of which are over A period of about 80-120 hours.

Key words: Acridine N-oxide, Nitroxyl radical, ESR, Photoreaction
