Abstract

Inventia se refera la un procedeu pentru prepararea unor alfa-haloalchilamide cu formula generala I: (vezi formula) de preferinta optic active, în care R reprezinta alfa-haloalchil cu 1...8 atomi de carbon, R2 si R3 identici sau diferiti, reprezinta radicali alchil cu 1...8 atomi de carbon, prin reactia unui ester cu o amina, caracterizat prin aceea ca un ester cu formula generala II: (vezi formula) în care R1 reprezinta un radical alchil cu 1...8 atomi de carbon, iar R are semnificatiile susmentionate reactioneaza cu o amina cu formula generala III: (vezi formula) în prezenta a circa 50...300% molar fata de ester a unui promotor ales dintre trihalogenura de ziconiu sau tetrahalogenura de titan.
