Irradiation of 2-methyl- (1c) and 2,2-dimethyl-3-phenyl-2H-azirine (1d) in benzene solution in the presence of carbon dioxide yields 2-methyl-4-phenyl- (3c) and 2,2-dimethyl-4-phenyl-3-oxazolin-5-one (3d), respectively. Similar cycloadducts are observed (see table) when 2,3-diphenyl-2H-azirine (1b) and 1d are irradiated in the presence of phenylisocyanate, o-tolylisocyanate, phenylisothiocyanate or
在二氧化碳的存在下,在苯溶液中照射2-甲基-(1c)和2,2-二甲基-3-苯基-2H-叠氮基(1d)产生2-甲基-4-苯基-(3c)和2, 2-二甲基-4-苯基-3-恶唑啉-5-酮(3d)。类似cycloadducts观察到(见表格)时2,3-二苯基2H -azirine(1B)和1D在异氰酸苯酯的存在下照射,邻tolylisocyanate,异硫氰酸苯酯或二-邻甲苯基碳二亚胺。
