Synthesis of meso-ionic anhydro-2-arylamino-1,3,4-thiadiazolium hydroxides and the rearrangement of meso-ionic 1,3,4-thiadiazoles to meso-ionic 1,3,4-triazoles
Abstract
The synthesis of anhydro-2-arylamino-1,3,4-thiadiazolium hydroxides (II), a new class of meso-ionic heterocycle, and two routes for their conversion into anhydro-2-mercapto-1,3,4-triazolium hydroxides (I) are described.
