    Abstract: Bifunctional phenyl iso(thio)cyanate derivatives (I) are new. Also new are aniline and nitrobenzene derivative intermediates (II) and (V). Bifunctional phenyl iso(thio)cyanate derivatives of formula W=C=N-Ar-CO-NH-SO 2-A (I) are new. W : O or S; Ar : phenylene (optionally substituted by one or more of halo, 1-4C haloalkyl and CN), and A : NH 2 or the residue of a primary or secondary amine. Independent claims are also included for: (a) preparation of (I); (b) new aniline and nitrobenzene derivative intermediates of formulae H 2N-Ar-CO-NH-SO 2-A (II) and O 2N-Ar-CO-NH-SO 2-A (V), and (c) preparation of 4-(sulfamidocarbonyl-phenyl)-1,2,4-triazolinedione derivatives of formula (VI) by reacting an ester of diaza-ester of formula R 4>-NH-NR 3>-C(W')OR' (VII) and cyclizing the obtained urea derivative of formula R'O-C(=W')-N(R 3>)-N(R 4>)-C(=W)-NH-Ar-CO-NH-SO 2-A (VIII). [Image] W' : O or S; R 3>, R 4> : H, CN, NH 2, 1-6C alkyl, 1-6C haloalkyl, 1-6C alkoxy, 1-6C haloalkoxy, 3-7C cycloalkyl, 2-6C alkenyl, 2-6C haloalkenyl, 3-6C alkynyl, benzyl, OR 5> or (1-3C) cyanoalkyl, or R 3> + R 4> : a group completing 4-7 membered heterocyclyl optionally interrupted by S, O, NR 6> or N and optionally substituted by one or more of halo or 1-4C alkyl; R 5> : H, 1-6C alkyl, 1-6C haloalkyl, 3-7C cycloalkyl, 2-6C alkenyl, 3-6C alkynyl, optionally substituted phenyl or optionally substituted benzyl; R 6> : H, 1-6C alkyl, 3-6C alkenyl or 3-6C alkynyl, and R' : 1-4C alkyl. ACTIVITY : Herbicide. MECHANISM OF ACTION : None given.

    Abstract: The invention relates to a method for producing 2-chloromethylphenyl acetic acid derivatives of formula (I), in which X represents C1-C4 alkoxy or methylamino, by cleaving the ether bonds in compounds of formula (II), in which R represents C1-C4 alkyl, C1-C4 alkoxy, C1-C2 alkyl halide, C1-C4 alkylcarbonyl, C1-C4 alkylcarbonyloxy, halogen, nitro or cyano, and X has the above-mentioned meaning. The inventive method is characterized in that the transformation takes place in the presence of hydrogen chloride and of an inert solvent, and in that a catalyst selected from the group comprised of: iron, indium or halogenides, oxides or triflates thereof is added to the reaction mixture.

    Abstract: A process for preparing oxime ethers of the formula I,in which the substituents R and R can be identical or different and can each be cyano, alkyl, haloalkyl, cycloalkyl, phenyl and naphthyl, and R can be alkyl, by alkylation of oximes of the formula IIunder basic conditions with an alkylating agent from the group of alkyl halides, dialkyl sulfates and dialkyl carbonates, wherein the reaction is carried out in a mixture consisting of5 to 25% by weight of polar aprotic solvents selected from the group of nitrites, N-alkylpyrrolidones, cyclic urea derivatives, dimethylformamide and dimethylacetamide,55 to 95% by weight of nonpolar solvents selected from the group of aliphatic hydrocarbons, aromatic hydrocarbons, alkyl alkylcarboxylates and ethers, and0 to 25% by weight of water, the contents thereof totaling 100%.
