摘要：

The 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 observe depending o the reaction temperature and the isocyanates. The results obtained enable us to correct some confusions in the literature about thioureas of pyrazoles.
