It has been established that iodocyclization of 3-(2-methyl-2-propenyl) thio-4-methyl-1,2,4-triazole occurs regioselectively with annelation of the thiazole ring, 3-(3-methyl-2-butenyl)thio-4-methyl-1,2,4-thiazole with annelation of the thiazine ring, and 3-allylthio-4-methyl-1,2,4-triazole with annelation of both rings to form derivatives of [1,3]thiazolo[3,2-b][1,2,4] triazolium and [1,2,4]triazole[5,1-b][1,3]thiazinium iodides. © 2011 Springer Science+Business Media, Inc.
