A novel 3,4-dihydro-5-methylene-1,2,4-triazole and its reactions with acrylonitrile and sulphene (thioformaldehyde S,S-dioxide) to form spiroaziridines
Abstract
The dihydro-1,2,4-triazole (2), prepared by oxidation of the amidrazone (1), reacts with acrylonitrile and with sulphene (CH2SO2) to afford spiroaziridines (5) and (6), respectively.
