â¢Photoinduced reactions of chloroacetone were investigated in solid Ar.â¢UV irradiation caused the rotamerization from gauche- to syn-chloroacetone.â¢Isomerization to hypochlorous acid 1-methylethenyl ester was observed.â¢Photolysis product, cyclopropanoneâ¯HCl complex, was measured.
The UV light-induced reactions of chloroacetone in a cryogenic Ar matrix were investigated using infrared spectroscopy. The photoinduced isomerisations of gauche-chloroacetone to syn-chloroacetone and hypochlorous acid 1-methylethenyl ester were confirmed by comparing the experimental and calculated spectra. In addition, the photolysis products were found to be CH2CO and a cyclopropanoneâ¯HCl complex. The cyclopropanoneâ¯HCl complex was further decomposed into CH2CH2, CO and HCl. The hypochlorous acid 1-methylethenyl ester was further isomerized to 2-chloro-2-methyloxirane.
