Acyl chlorides are split into acyl and chlorine radicals by light of wavelength 254 my. Since the dissociation energy of the chlorine-hydrogen bond is considerably larger than that of the acyl-hydrogen bond, substitution of the substrate by acyl radicals is observed on irradiation of acid chlorides.
CF 3 O 2 CF 3 was photolyzed at 254 nm in the presence of CO in 760 torr N 2 or air at 296 K in a static reactor. In N 2 , the products CF 3 OC(O)C(O)OCF 3 and CF 3 OC(O)O 2 C(O)OCF 3 were detected by FTIR spectroscopy. In air, the only observed products were CF 2 O and CO 2 and a chain process, ini
