Abstract
Inventia se refera la un procedeu pentru prepararea unor derivati de acizi 1,3,4-tiadiazol-2-carboxilici cu formula I: (vezi form. in desc.)în care R repreprezinta alchil cu 1....6 atomi de carbon, alchenil cu 2....6 atomi de carbon, alchinil cu 2....6 atomi de carbon, R1 reprezinta alcoxicarbonilbonil cu 1....6 atomi de carbon în grupa alcoxi, aminocarbonil, alchilaminocarbonil cu 1....8 atomi de carbon în grupa cicloalchil de carbon în grupa cicloalchil, dialchilaminocarbonil cu 1....8 atomi de carbon în fiecare grupa alchil, ciclogexilmetilaminocarbonil, alcoxialchilaminocarbonil, moroflinocarbonil, pirolidinocarbonil, piperidinocarbonil sau cian si n reprezinta 1 sau 2. Procedeul consta în aceea ca, un compus cu formula II: (vezi form. in desc.)în care R si R1 au semnificatiile de mai sus este oxidat cu permanganat de potasiu, utilizînd pentru echivalenti de oxidare, în mediu de acid acetic si apa, la temperaturi cuprinse între 10 si 70 degree C.
