In order to search for efficient sulfonylurea herbicides, the title compounds were designed by introducing triazolinones into some known sulfonylurea structures. 23 novel sulfonylurea compounds had been synthesized and characterized by 1H NMR, HRMS and X-ray diffraction. Herbicidal activities of title compounds were determined by pot-culture method. IC50 values of some effective sulfonylurea compounds were tested by culture dish method. It was found that compound 5h attained the super-active level which was comparable to the controls as triasulfuron and cinosulfuron. It was worthy to note that compound 5h had potent inhibitory activity against Echinochloa crusgalli by pot-culture method at 3.75 g/ha.

Key words: sulfonylurea, triazolinone, synthesis, crystal structure, herbicidal activity
