Abstract: Eight new title compounds 5a-h were synthesized by condensation of 2-chloro-substituted benzothiazole and α-hydroxy alkyl (phenyl)phosphonate in yield of 51%~95%. Their structures were characterized by elemental analysis. IR. 1HNMR and MS measurements.and their herbicidal activities were tested.

Key words: organophosphorus compound, substituted benzothiazol-2-yl-oxy phosphonate, herbicide, synthesis
