The reactions of β-azolylenamines with sulfonyl azides in acetonitrile furnished 1H-4-(azol-5-yl)-1,2,3-triazoles in yields of 52-93%. β-Benzoylenaminones and β-nitroenamine of type 1 also reacted with tosyl azide to form the same type of products 3, proving the generality and efficiency of the method for the synthesis of N-unsubstituted 1,2,3-triazoles. However, the reactions of 3-(1-aryl-1,2,3-triazol-5-yl)enamines with tosyl azide in the absence of a solvent afforded a mixture of (E)-1-dimethylamino-2-tosylaminoethenes and N,N-dimethyl-N’-tosylformamidine in yields of 40-50 and 20 %, resp. The formation of a variety of compounds from the reactions of enamines with sulfonyl azides is rationalized by the various possible transformations of the intermediate 5-dimethylamino-1,2,3-triazolines.
European Journal of Organic Chemistry published new progress about 14544-45-7. 14544-45-7 belongs to triazoles, auxiliary class Triazoles, name is 5-Nitro-1H-1,2,3-triazole, and the molecular formula is C2H2N4O2, Application of 5-Nitro-1H-1,2,3-triazole.
