An improved synthesis of 1,2,4-triazoles using Ag2CO3

An improved synthesis of 1,3,5-trisubstituted 1,2,4-triazoles via Ag2CO3 mediated cyclization of triazenes has been developed. This approach is flexible and compatible with a wide range of functional groups. The reaction was complete within 3 h and the products were isolated in moderate to high yields. The influence of the β-substituents of the amines on the triazole formation was also studied. (C) 2000 Elsevier Science Ltd.

An approach to 1-aryl-1,2,4-triazoles

A series of different 1,3,5-trisubstituted 1,2,4-triazoles 9 have been readily prepared by simple oxidation of corresponding N-alkylamide arylhydrazones (amidrazones) 5 with hydrogen peroxide or potassium permanganate.
