Abstract
The reaction of 1, 1'-thiocarbonyldiimidazole and 1, 1'-thiocarbonylbis (1, 2, 4-triazole) with several aldonitrones has been found to afford thioamides in good yield. Several 1, 1'- thiocarbonylbisazoles, which have been shown to undergo Diels-Alder additions with dienes to give cyclic and bicyclic adducts, can be further converted to mercapto esters, thiapyrans, and thiapyranones in good yield.
