Abstract: Invenţia se referă la procedeul de obţinere a cis-2-(1H-1,2,4-triazol-1-il-metil)-2-(halogenfenil)-3-(halogenfenil)-oxiranei cu formula I:Scopul invenţiei îl reprezintă sporirea randamentului produsului cu destinaţie specialăşi minimizarea consumului pentru purificare.Procedeul se efectuează pe calea epoxidării Z-3-(1H-1,2,4-triazol-1-il)-2-(halogenfenil)-1-(halogenfenil)-propenei cu acid permaleinic, reducând-o ulterior. În calitate de reducător este folosit hidrosulfitul de sodiu, ditionitul de sodiu sau tiosulfatul de sodiu sau hidrogenul în prezenţa nichelului Renei. Reducătorul se adaugă la amestecul reactant într-o cantitate excedentă faţă de cantitatea necesară pentru descompunerea acidului permaleinic, posibil prezent.

Abstract: The invention concerns a method of preparing .alpha.-methoxyiminocarboxylic acid methylamides of formula (I)(X = nitro, trifluoromethyl, halogen, alkyl or alkoxy; n = 0, 1, 2, 3 or 4; Y = an organic carbon group) by the Pinner reaction of cyanoketone of formula (II) with an alcohol, followed by reaction of the ester of formula (IV) formed in the Pinner reaction with hydroxylamine to give an oxime of formula (V), methylation of (V) to give an oxime ether of formula (VI) and subsequent reaction of (VI) with methylamine. The invention also concerns the intermediates used in the method.

Abstract: A process for preparing halomethylbenzoyl cyanides I Ph-CO-CNI (Ph=phenyl radical substituted by chloromethyl or bromomethyl which, if desired, can additionally carry 1-4 further radicals) by reacting halomethylbenzoyl chlorides II Ph-CO-ClII with an alkali metal cyanide or transition metal cyanide, if appropriate in an organic diluent, and novel halomethylbenzoyl cyanides I' I' (X=halogen, C1-C4-alkyl, C1-C4-alkoxy, CF3, C1-C5-alkyl-(C1-C5-alkyl)hydroxyimino or C1-C5-alkyl-(C2-C5-alkenyl)hydroxyimino; m=0 to 4 and Y=chloromethyl or bromomethyl) are described. The halomethylbenzoyl cyanides I are important intermediates for the synthesis of plant protection agents.

Abstract: Described is a process for the preparation of a particulate tetrahydro-3,5-dimethyl-1,3,5-thiadiazine-2-thione product by combining a first aqueous solution comprising methylammonium N-methyldithiocarbamate with a second aqueous solution comprising formaldehyde, followed by separation and drying of the resulting solid, which comprises combining the first and the second aqueous solutions in such a way that the ratio between the concentrations of dithiocarbamate functions and of formaldehyde is essentially constant in the reaction mixture over time during the duration of the reaction.
