Preparation of dithiadiazafulvalene precursors: 2-piperidino-2,3-dihydro-1,3-thiazoles or 2-unsubstituted 2,3-dihydro-1,3-thiazoles from the reduction of the corresponding 2-piperidino mesoionic thiazoles

3-aryl-4-alkylthio-5-aryl- or -alkyl-2,3-dihydro-1,3-thiazoles 10 have been prepared starting from mesoionic 5-alkyl- or 5-aryl-2-piperidino-1,3-thiazole-4-thiolates 6. After alkylation of the mesoioniccompound, the best conditions to isolate these two dihydrothiazoles were established from a mechanistic study of the reduction. Compound 8 is known to give dithiadiazafulvalenes through its thiazolium tetrafluoroborate
