Abstract
NEW MATERIAL:An N'-4-phenetyloxyphenyl N,N-dimethylurea derivative shown by the formula I (X is H or halogen; R is H, lower alkyl, halogen, etc.; n is an integer of 1W2).
EXAMPLE: N'-4-[2-(4-Methylphenyl)ethoxy]phenyl N,N-dimethylurea.
USE: A selective herbicide. Having strong destroying effects on various kinds of weeds by photosynthesis inhibiting actions and selectivity for rice plant. Having also selectivity for other important crops. Low toxicity. Useful even for a nonagricultural land.
PROCESS: A 4-phenetylthioxyphenyl isocyanate derivative shown by the formula II is reacted with dimethylamine in an organic solvent, e.g., benzene, etc., and, if necessary, under cooling or heating, to give a compound shown by the formula I in high yield.
