Abstract

Sulfonylation of 1,2,3-thiadiazolecarboxylic acid amidines in the presence of a base was found to be accompanied by the Cornforth rearrangement of the 1,2,3-thiadiazole ring into 1,2,3-triazole leading to the formation of 2-substituted 1,2,3-triazoles in high yields.

Keywords

N-sulfonyl amidines, 2-sulfonyl-1,2,3-triazoles, sulfonyl chlorides, 1,2,3-thiadiazoles, rearrangement.
