Solvent polarity controls oxidizing species in the photosensitized oxidation of N,N-dibenzylhydroxylamine
Abstract
A kinetic analysis of the 9,10-dicyanoanthracene-sensitized photooxidation of N,N-dibenzylhydroxylamine, giving α-phenyl-N-benzylnitrone and hydrogen peroxide in quantitative yields, reveals the participation of superoxide in acetonitrile and singlet oxygen in carbon tetrachloride as the major oxidizing species.
