deriving from the heterolytic C−S bond cleavage in the sulfoxide radical cations (alcohols, R1R2R3COH, and acetamides, R1R2R3CNHCOCH3) accompanied by sulfur-containing products (phenyl benzenethiosulfinate, diphenyl disulfide, and phenyl benzenethiosulfonate). By laser irradiation, the formation of 3-CN-NMQ• (λmax = 390 nm) and sulfoxide radical cations 1•+, 2•+, and 5•+ (λmax = 550 nm) was observed within
