    Abstract: 1424784 Oxime ethers BADISCHE ANILIN- & SODA-FABRIK AG 19 April 1973 [22 April 1972] 18925/73 Heading C2C The invention comprises oxime ethers of Formula (I) in which X denotes halogen and R denotes hydrogen, an alkali metal or an acyl radical of formula R 1 CO in which R 1 denotes hydrogen or a substituted or unsubstituted aliphatic or cycloaliphatic hydrocarbon radical or a carbocyclic aryl radical optionally substituted by halogen, NO 2 , CF 3 , CN or alkyl, alkoxy or alkylthio radical having 1-4 carbon atoms. Those compounds in which R is hydrogen or an alkali metal may be prepared by reacting a solution or suspension of a 3,5-dihydro-4-hydroxybenzaldehyde oxime with 2-chloro-5-nitro-benzonitrile in the presence of an excess of alkali metal alcoholate as condensing agent and, if desired, acidifying the alkali metal salt obtained. The compounds of Formula (I) may be treated with an alkylating or acylating agent to replace the group R by a group R 2 which is alkyl, haloalkyl, alkoxyalkyl, aryl, alkoxy carbonyl, alkoxyalkoxycarbonyl, alkylmercaptocarbonyl, alkylmercaptoalkoxycarbonyl, optionally substituted phenoxycarbonyl, mono-substituted carbamoyl or N,N-disubstituted carbamoyl, alkyl sulphonyl or optionally substituted arylsulphonyl, mono- or di-alkyl sulphamoyl; or optionally substituted monoaryl- or alkylarylsulphamoyl. The compounds of Formula (I) above and some of those in which R is replaced by R 2 may be used as active agents in herbicidal compositions.
