Irradiation of 2,2-dimethyl-3-phenyl- (1c) and 2,3-diphenyl-2H-azirine (1d) in benzene solution in the presence of ketene (5) yields 2,2-dimethyl-4-phenyl- (6) and 2,4-diphenyl-5-methylen-3-oxazoline (7), respectively. Similar cycloadducts (9a to d) are observed when 3-phenyl- (1a), 2-methyl-3-phenyl-2H-azirine (1b), 1e and Id, respectively are irradiated in benzene solution in the presence of azibenzile (8).
