Effect of para-substituents on the photochemical ring-opening reactivity of 1-(p-substituted-benzoyl)aziridines in methanol
Abstract
Photolysis of 1-(p-substituted-benzoyl)aziridines (1a–e) in Ar-purged methanol led to N-(2-methoxyethyl)benzamides (3b–e) as the methanolysis products and/or N-ethylbenzamides (2a and b). Penta-1,3-diene quenched the formation of (2a and b) but not (3b–e).
