Abstract
NEW MATERIAL:A compound shown by the formula I (R is ethoxy, carbonylmethyl, or cyanomethyl; n is 1 or 2).
EXAMPLE: Bis[N-(ethyoxycarbonylmethyl)diphenylphosphonomethylamino] sulfide.
USE: A herbicide. Effective against "Echinochloa crus-galli" Beauv. var. "praticola" OHWI, Yerba de tajo, etc.
PROCESS: A phosphonomethylamino derivative shown by the formula II is reacted with a sulfur chloride compound shown by the formula (S)nCl2 in a solvent, e.g., dithyl ether, etc. in the presence of a base (e.g., triethylamine, etc.), to give a compound shown by the formula I. The reaction temperature is -70 to 50°C, preferably -20°C to room temperature. A herbicide is obtained by comprising the compound shown by the formula I as an active ingredient, and its dilution ratio and the amount of scattering is 50W200l/10a. The herbicide is not effective at all by soil treatment, useful for controlling noxious weeds in plowded fields, tree gardens, and mulberry fields, etc.
