Abstract
NEW MATERIAL:4-(4-Hydroxyphenoxy)-2-pentenoic acid derivatives of formula I (R is H or alkyl).
EXAMPLE: 4-(4-Hydroxyphenoxy)-2-pentenoic acid ethyl ester.
USE: A starting material of e.g. 4-[4-(4-trifluoromethylphenoxy)phenoxy]-2-pentenoic acid ethyl ester which is a herbicide effective to grasses from the pre-sprouting stage to the grown stage considerably safe to main crops, e.g. soybeans, radishes etc., and esp. effective to a hardly exterminable weed, ginsong. The compound itself is effective for prevention and extermination of rice blast and sheath blight.
PROCESS: A compound of formula I is obtained by the reaction of hydroquinone with 4-halogeno-2-pentenoic acid and its derivative in a solvent, e.g. water, acetone etc., at -20°CW150°C in the presence of a base.
