Abstract
Invenţia se referă la un procedeu de obţinere a 2-mercapto-1,3,4-oxadiazolilor cu formula generală Iîn care R reprezintă un radical aromatic ori un radical heterociclic, folosiţi ca fungicide, stabilizatori ai imaginilor fotografice etc.Esenţa invenţiei constă în aceea că procedeul de obţinere a 2-mercapto-1,3,4-oxadiazolilor constă în încălzirea hidrazidelor acizilor aromatici ori heterociclici cu un agent cu conţinut de sulf, în acest caz tratarea hidrazidelor corespunzătoare cu disulfură de tetrametiltiuram (DTMT) se efectuează în raportul molar de 2: (1 - 1,3).Rezultatul tehnic al invenţiei constă în utilizarea disulfurii de tetrametiltiuram în calitate de agent pentru ciclizare, ce a făcut posibilă accelerarea reacţiei, mărirea randamentului compuşilor cu 20-30% şi micşorarea de 10-15 ori a timpului necesar pentru reacţie.
