Synthesis of PyrazolyldithiocarbonatesThe reaction of 3-amino-pyrazole 1 with carbondisulfide and alkylating agents in basic conditions to yield different dithiocarbonates 2-8 was studied. The dithiocarbonates 2a react with isocyanates to form 1-acyl-5-acylamino-pyrazoles 9-10. Acyl migrations were observed depending on the reaction temperature and the isocyanates.The results obtained enable us to correct some confusions in the literature about thioureas of pyrazoles.
