[Kinetic study of the cyclization of the addition compound of ethyl mercaptoacetate on benzylideneacetophenone]. / Etude cinétique de la cyclisation du composé d'addition du mercaptoacétate d'éthyle sur la benzylidèneacétophénone.

The study of the kinetic of cyclisation reaction of the additional compound of the mercaptoacetic ethylester on a benzylideneacetophenone was proposed. With the chromatography a retro-Michael reaction was obtained. The H NMR alone permitted to show the order 1 for the kinetic of cyclization and according to the amine used like reaction catalyst, two diastereoisomers could be formed.
