Abstract
Reaction of 3-isothiocyanato-2-propeniminium perchlorates 1 with hydro xylamine gives 1-hydroxy-2(1H)-pyrimidine-2-thiones 2 which can be O-a cylated. The resulting 1-acyloxy-2(1H)-pyrimidine-2-thiones 4 are nove l precursors for organic radicals. Their photochemical homolysis is st udied and affords disulfides 5, 2-alkylthiopyrimidines 6 and alkanes 7 and 8.
