The regioselective iodocyclization reaction of 3-aryl-5-(prop-2-ynylthio)-1H-1,2,4-triazoles is described for the first time. The iodocyclization reaction of 3-aryl-5-(prop-2-ynylthio)-1H-1,2,4-triazoles using molecular iodine afforded diiodo-compound which on CuI-catalyzed intramolecular C-N coupling reaction gave six-membered 2-aryl-5H-[1,2,4]triazolo[5,1-b][1,3]thiazines, whereas, the five membered 3-aryl-5,6-dihydrothiazolo[2,3-c][1,2,4]triazoles were obtained exclusively when the iodocyclization reaction of 3-aryl-5-(prop-2-ynylthio)-1H-1,2,4-triazoles was carried out using NIS.

The facile and regioselective synthesis of 2-substituted 5- methylthiazolo[3,2-b]triazoles has been performed by the catalytic action of H2SO4 on the corresponding propynylthio derivatives.

The facile and regioselective synthesis of 2-substituted 5-methylthiazolo[3,2-b]-s-triazoles has been performed by the catalytic action of NaOH on 3-propynylthio-s-triazoles.
