Abstract

(1) of this reaction, we required access to hetero-fused 1, 2, 3-thiadiazoles. The usual preparation of fused 1, 2, 3-thiadiazoles is by diazotization of 0-amino These thiols are available from o-chloronitrobenzenes, benzothiazoles, or by the Herz reaction3 of anilines with sulfur monochloride. We perceived that heterocyclic amines would be the most easily accessible precursors and therefore we chose to examine the hetero-Herz reaction. While ...
