Irradiation of 2-diazoacenaphthenone (1) in nitriles such as acetonitrile, propionitrile, benzonitrile, p-tolunitrile, and acrylonitrile afforded the corresponding 2-substituted acenaphtho[l,2-d]oxazoles (3). In pyrolysis of 1 in benzonitrile 2-phenyloxazole derivative 3c was formed, together with traces of 2,2’-diacenaphthylidene-1,1’-dione.
