Abstract
Inventia se refera la un procedeu pentru prepararea unor esteri de acid 3-acilazopropionic cu formula I din pag.1 a descrierii, în care R1 reprezinta un radical alchil cu 1...6 atomi de carbon, R2 reprezinta un radical alcoxi cu 1...4 atomi de carbon sau gruparea amino, si anume esterii de acid acrilic cu formula II, în care R1 are semnificatiile sus-mentionate, în cantitati echimoleculare, se trateaza cu derivati hidrazinici cu formula III, în care R2 are semnificatiile sus-mentionate, în cantitati echimoleculare, la temperaturi cuprinse între 0 si 50 degree C si/sau în prezenta unui catalizator bazic sau acid ales dintre hidroxizi sau alcoolati de metale.
