Abstract
NEW MATERIAL:The compound of formulaI(R1 and R2 are lower alkyl; R3 is lower alkyl or lower alkenyl; X is H or halogen).
EXAMPLE: Bis[3-(N-ethoxypropionimidoyl)-6-ethyl-2-oxo-2H-pyran-4-yl]terephthalate.
USE: Herbicide having excellent herbicidal activity against gramineous weeds such as lower spear grass, water foxtail, etc. by soil treatment or by scattering to the leaves or stalks, and harmless to the leguminous crops such as adzuki bean, soybean, etc. which are liable to be damaged with various other herbicides. It is non-toxic to man, animals, and fish, and has high stability for the storage, production and preparation.
PROCESS: The compound of formulaIis prepared by reacting the compound of formula II e.g. 3-(1-N-ethoxyaminoethylidene)-6-ethyl-3,4-dihydro-2H-pyran-2,4- dione, with terephthaloyl dichloride.
