Abstract

NEW MATERIAL:To p-benzyloxybenzoic acid derivative of formulaI(X is halogen or lower alkyl; n is 0 or 1W5; Y is OH, OR1 or NR1R2; R1 is lower alkyl, lower alkenyl or lower alkynyl; R2 is H, OH, lower alkoxy, etc.).
EXAMPLE: 4-(4-Chlorobenzyloxy)benzoic acid methyl ester.
USE: Herbicide having excellent herbicidal activity against cockspur-grass, star wort, umbrella plant, etc., and harmless to rice plant.
PROCESS: The comound of formulaIis prepared, e.g. by reacting the benzyl halide of formula II (Hal is halogen) with the p-hydroxybenzoic acid derivative of formula III in the presence of dehydrohalogenating agent such as sodium carbonate at 50W150°C.
