Abstract: Phenyl-3-(p-toluenesulfonyl) thiourea was reacted with triphenylphosphite and substituted benzaldehydes to give 1-(p-toluenesulfonyl)-2-oxo-2-phenoxy-3-aryl-1,4,2-di-azaphospholidin-5-thiones in anhydrous toluene. The by-reactions of the preparation process were discussed. The structures of new compounds were confirmed by elementary analysis,1H NMR, 31P NMR, MSand IRspectra. The results of preliminary bioassay show that they possess a herbicidal activity at 1.5kg/ha in post-emergent tests against six kinds of plants including Barnyard-grass, Oat, Rape, and Alfalfa,etc.

Key words: 1,4,2-Diazaphospholidin-5-thione, Synthesis, Herbicidal activity
