Abstract

NEW MATERIAL:Phenylhydantoin derivatives of formula I (X is H, nitro, lower alkyl, phenyl, halogen; Y is halogen; n is 1W3).
EXAMPLE: 3-(3,4-Dichlorophenyl)-1-methyl-5-(4-nitroimidazol-1-yl)hydantoin.
USE: Herbicide: they show strong activity against weeds on both pre-emergence and post-emergence; however, especially show remarkable activity on the post-emergence. Further, they are scarecely injurious to crops such as cotton or rice plant and can be used safely. Especially, they show high selectivity when stems and leaves of cotton are treated therewith.
PREPARATION: The reaction of 5-bromo-3-(3,4-dihalophenyl)-1-methylhydantoin with an imidazole of formula II is conducted in the presence of a base such as potassium carbonate in a solvent or with no solvent, when necessary, with heat to give the compound of formula I.
