Photoreactions of 1,2-bis[2,4,6-tris(trifluoromethyl)phenyl]diphosphene and 1-(2,4,6-tri-t-butylphenyl)-2-[2,4,6-tris(trifluoromethyl)phenyl]diphosphene were studied. The latter diphosphene gave formally an intramolecular cyclization product by photoirradiation, whereas the former diphosphene showed no change on irradiation.
