Abstract

A number of 1,4-diphenyl-1,4,2-diazaphospholidin-5-one-2-oxides (4) have been synthesized by the Mannich-type reaction of 1,3-diphenylurea (1), substituted benzaldehydes (3) and triphenyl phosphite (2) with anhydrous toluene as the solvent. Compounds 4 have been confirmed by microanalyses and spectroscopic methods. The bioassay indicates that some of compounds prepared have good selective herbicidal activity and the quantitative structure-herbicidal activity relationship (QSAR) of compounds 4 has also been studied.
