Abstract
NEW MATERIAL:A substituted phenylhydantoin derivative shown by the formula I(R is methyl, ethyl, n-, iso-propyl, n-, iso-, sec-, tert-butyl, allyl, propargyl, cyclopropyl).
EXAMPLE: 3-(2-Fluoro-4chlorophenyl)-1-iso-propylhydantoin.
USE: A herbicide. having strong berbicidal effect on broadleaf weeds and gramineous weeds, having low phytotoxicity to soybeans, cotton, etc., and selectivity, exhibiting strong activity against perennial weeds, e.g., bulrush, etc. by treatment before germination and in growth period, and having strong herbicidal activity against many kinds of weeds.
PROCESS: 2-Fluoro-4-chlorophenylisocyanate is reacted with an amine shown by the formula II (R' is CN, hydroxycarbonyl, or alkoxy-carbonyl) to give a compound shown by the formula III, which is subjected to ring formation to give a compound shown by the formulaIin the presence of a mineral acid as a catalyst.
