| abstract | 1414213 Cyclic N-phenyl-urea derivatives ROUSSEL UCLAF 6 Aug 1973 [4 Aug 1972] 37189/73 Heading C2C The invention comprises an N-phenyl-urea derivative of the general Formula (I) wherein: A represents a straight- or branchedchain alkylene group containing from 2 to 6 carbon atoms; X, which may be at any available position in the benzene ring, represents a hydrogen or halogen atom, a trifluoromethyl radical, a nitro group, an acyl radical containing from 1 to 6 carbon atoms, an alkyl or alkoxy radical each containing from 1 to 6 carbon atoms, or an unsubstituted or halo-substituted alkenyloxy radical containing from 2 to 6 carbon atoms; Y, which may be at any available position in the benzene ring, represents a hydrogen or halogen atom, or an alkyl or alkoxy radical each containing from 1 to 6 carbon atoms; and R represents an alkoxy radical containing from 1 to 4 carbon atoms, an alkoxycarbonyl radical containing from 1 to 6 carbon atoms, or a chloroacetyl group. Compounds of general Formula (I) where R is an alkoxycarbonyl or monochloroacetyl group R<SP>1</SP>, may be prepared by reacting an appropriate N-phenyl cyclic compound of Formula (V) with an appropriate halide R<SP>1</SP>-Hal<SP>1</SP>, where Hal<SP>1</SP> is Cl or Br, in the presence of a strong base. Compounds of general Formula (I) where R is an alkoxy radical R<SP>2</SP> may be prepared either by condensing an appropriate N-R<SP>2</SP>-N<SP>1</SP>-phenylurea of general Formula (II) with an appropriate alkyl halide Z-A-Hal<SP>2</SP> where Z is a halogen atom or hydroxy group, and Hal<SP>2</SP> is a halogen atom, in the presence of a strong base, or by cyclizing an appropriate N-R<SP>2</SP>-N-substituted-alkyl-N<SP>1</SP>-phenyl-urea of general Formula (IV) in the presence of a base. The compounds of Formula (II) may be prepared by reacting an appropriate o-alkylhydroxylamine R<SP>2</SP>-NH 2 with an appropriate phenyl isocyanate of Formula (VI) The compounds of Formula (IV) may be prepared by condensing an appropriate phenyl isocyanate of Formula (VI) with an appropriate N-alkoxy-N-hydroxyalkyl-amine of formula R<SP>2</SP>-NH-A-OH to give a compound of Formula (III) and then reacting the latter with a chlorinating agent such as thionyl chloride, sulphuryl chloride or oxalyl chloride. The compounds of Formula (I) are used in herbicidal compositions for use in agriculture. |
