Abstract: A series of new 2-diethylamino-3-substituted phenylsulfonyl-1,3,2-oxazaphospholidine derivatives (Ⅰ) has been synthesized by the reaction of tris(diethylamino) phosphine with N-(β-hydroxyethyl) substitutedphenylsulfonamides. When was refluxed with sulfur in benzene, the 2-thiono derivatives (Ⅱ) was obtained conveniently.(Ⅰ) was easily oxidized in air and the diethylamino group could be substituted by phenoxy or other amino group giving the corresponding derivatives. Their 1H NMR and MS spectra have been discussed. Some of compounds (Ⅱ) have herbicidal activities.
