Abstract: Fifteen N'-(4, 6-disubstituted pyrimidin-2-ly)-2-thiophenesulfonylureas were synthesized from thiophene in 4 steps.Eleven of them are new compounds.Their structures were proved by 1H NMR, IR, MSand elementary analysis.Their herbicidal activities have been determined.It is found that some of them show a good herbicidal activity.

Key words: Pyrimidine, Thiophenesulfonylureas, Herbicidal activities
