Abstract
NEW MATERIAL:α-[4-(5-Trifluormethyl-2-pyridyloxy)phenoxy]methylmalonic acid derivative of formula I (X is H, Cl; R1 and R2 are salt-forming atom, salt- forming residue, lower alkyl).
EXAMPLE: α-[ 4-( 5-Trifluoromethyl-2-pyridyloxy )phenoxy ]methylmalonic acid diethyl ester.
USE: Herbicide having selective herbicidal effect to true grass weeds and harmless to broad leaved plant. Applicable to plow field, paddy rice field, orchard, etc., by leaf and stalk treatment, soil treatment, etc.
PROCESS: The compound I is prepared by reacting a compound II (Hal is halogen) with a compound III in a solvent such as dimethylformamide, etc., in the presence of an alkaline substance such as NaOH, etc., at 50W150°C.
