Fourteen N’- (4,5,6-Trisubstitued pyrimidin-2-y1) -2-chloroacetylureas and fourteen N-[N’- (4,5,6-trisubstitued pyrimidin-2-yl) acetylureido] benzoic sulfimide derivatives were synthesized. Among them twenty-seven are new compounds and their structures have been confirmed by 1HNMR, IR, MS and elemental analysis. The preliminary biological tests showed that some of the target compounds have excellent inhibitory activities against barnyard grass and rape, and the others have a good regulating activity for plant growth.
