Abstract
NEW MATERIAL:A diphenyl ether compound of formula I (R is 2,4-dichlorophenyl or 4-trifluoro-methylphenyl; R1 is lower alkyl; R2 is H or COR3; R3 is lower alkyl or lower alkoxy).
EXAMPLE: Methyl-3-oxo-4-[4'-(4"-trifluoromethylphenoxy)phenoxy]-pentanoate.
USE: Herbicide effective especially to true grass weeds such as cockspur-grass, large crab-grass, Johnson grass, etc. independent of the species and safe to broad-leaved crops such as soybean, beet, radish, etc.
PROCESS: The compound of formula I is prepared by reacting an acid halide of formula II (Hal is halogen) with a compound of formula III in the presence of a dehydrohalogenating agent such as magnesium alcoholate.
