Abstract
Photochemical reaction of 3-cyclohexyl-4-phenylsydnone (4) in nitrogen atmosphere afforded 2-cyclohexyl-4,5-diphenyl-1,2,3-triazole (5), 1,2-biscyclohexylazo-1,2-diphenylethylene (6) and 4-cyclohexyl-2-phenyl-Δ2-1,3,4-oxadiazoline-5-one (7). The results showed that the reaction of 4 in the presence of carbon dioxide, carbon disulfide and dimethyl acetylenedicarboxylate proceeded via nitrile imine intermediate. Irradiation of 3-t-butyl-4-phenylsydnone (11) afforded 1-benzoyl-2-t-butyl-4-phenyl-1,2-diazetidine-3-one (12). Variation of the absorbance of 4 at the longest wavelength with irradiation was affected by 1,3-pentadiene, but not that of 11. This shows that the excited triplet state is responsible for the photochemical reaction of 4.
