| Abstract: | Primisulfuron-methyl was prepared by 2-amino-4,6-bis(difluoromethoxy)-pyrimidine(DMAP) and 2-methoxycarbonylphenylsulfonylisocyanate.As a key reagent,DMAP was synthsied with fluorosulfonyldifluoro-acetic and 2-amino-4,6-dihydroxypyrimidine,Na2SO4 was used as catalyst and CH3CN was used as solvent.as a good herbicide.the Active effect of primisulfuron-methyl was studied in the room and in suburb. |
