摘要
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 beta-substituents of the amines on the triazole formation was also studied. (C) 2000 Elsevier Science Ltd. All rights reserved.
