    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 relates to a process for preparing 2-halopyridinecarboxamides of primary aromatic monoamines I which have a substituent other than hydrogen in the ortho-position to the amino group by reaction of 2-halopyridinecarbonyl chloride II with the aromatic monoamine I, which comprises carrying out the reaction in a solvent mixture comprising water and at least one water-immiscible organic solvent in the presence of none or less than 10 mol %, based on the 2-halopyridinecarbonyl chloride II, of a base other than I or II.
