Photolysis of 4-alkyl-5-amino-1-vinyl-4,5-dihydro-1H-1,2,3-triazoles gave not 3-alkylpyrroles but unexpected 2-alkylpyrroles in 80-83 percent yields.Similarly, 4,4-dimethyltriazole derivatives gave 2,2-dimethyl-2H-pyrroles in 70-74 percent yields. 1-Vinylaziridines were assumed as a possible intermediate of this anomalous reaction.
