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 specială şi 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.
