Abstract

NEW MATERIAL:The titled derivative of formula I (R1, R2 are lower alkyl, haloalkyl; R3 is substituted phenyl, substituted pyridyl).
EXAMPLE: Methyl 5-(2-chloro-4-trifluoromethylphenoxy)-2-nitrophenylmethylphosphinate.
USE: Herbicide for rice paddies: they show high herbicidal activity against annual and prennial weeds, especially against prennial weeds such as arrowheads. Further, their activity is prompt.
PREPARATION: For example, the reaction between a dinitrobenzene derivative of formula II and a dialkyl phosphonite of formula III is effected in the presence or absence of an inert solvent such as acetonitrile, preferably at room temperature for 30minW3hr.
