Abstract
The triplet states of O-acyl aromatic ketoximes, RCO2N=CR1R2 (I, II, and III), undergo homolytic cleavage into iminyl radicals, R1R2C=N·, and acyloxyl radicals, RCO2·. The triplet states have their excitation energies which are close to those of their parent ketones, R1R2C=O, and are abundant in π,π* character. The excitation energies are dissipated through cleavage of the N–O bonds.Keywords
