Abstract: A series of 1-(p-toluenesulfonyl)-2-phenoxy-3-aryl-4-phenyl-1,4,2-diazaphospholidin-5-one-2-oxides (2) has been synthesized by the. Mannich-type reaction of 1-phenyl-3- (ptoluenesulfonyl) urea(1), substituted benzaldehydes and triphenyl phosphite in anhydrous toluene. The side reactions were discussed. The structures of new compounds were characterized by 1H NMR, 31P NMR, elemental analysis, MS and IR spectra. The results of preliminary bioassay showed that the compound 2 possesses good selective herbicidal activity against rape.

Key words: diazaphospholidin-one, synthesis, herbicidal activity
