Abstract

1,257,415. Urea derivatives. FARBWERKE HOECHST A.G. 9 March, 1970 [7 March, 1969], No. 11139/70. Heading C2C. Novel urea derivatives of the general formula wherein R is an alkyl or cycloalkyl radical having from 2 to 4 carbon atoms and from 4 to 7 halogen atoms, at least two of which are fluorine atoms, R 1 is a hydrogen or chlorine atom, and R 2 is a hydrogen atom, or a methyl or methoxy group, are prepared by reacting either (a) a correspondingly substituted halogeno (cyclo) alkylphenyl isocyanate or halogeno (cyclo) alkyl-carbanilic acid chloride with either (i) methyl- or dimethyl-amine or with o-methyl- or O,N - dimethyl - hydroxylamine, (ii) o - methylhydroxylamine or N - methyl - hydroxylamine with subsequent alkylation of the reaction product at 10‹ to 90‹ C., or (iii) hydroxylamine - with subsequent dialkylation of the reaction product at 10‹ to 90‹ C., or (b) a correspondingly substituted halogeno (cyclo) alkyl-aniline with either (i) methyl isocyanate or dimethylcarbamic acid chloride, or (ii) dimethyl- or methylmethoxy-carbamic acid phenyl ester. The products may be used as herbicides.
