Rose bengal and tetraphenylporphin sensitized photooxygenations of 5, 6-dimethyl- (1a) and 5-methyl-6-phenyl-2, 3-dihydropyrazine (1b) yield 1-isocyano-2-(N-acetylamino)-ethane (2a) and 1-isocyano-2-(N-benzoylamino)-ethane (2b), respectively. 5,6-Diphenyl-2,3-dihydropyrazine (1c) is inert under the reaction conditions.
