About this product

Product Information

Dans ce travail, nous avons utilise la methode de la theorie de la fonctionnelle de la densite DFT combinee au fonctionnel B3LYP pour etudier deux types de reactions de Darzens qui conduisent aux esters glycidiques en deux phases (gazeuse et en solution). Ces deux types de reactions sont d'une part, celle qui correspond a l'interaction entre le dihalogenoacetate d'isopropyle ou l'halogene est le chlore et ou le brome avec l'isobutyraldehyde (serie aliphatique) en utilisant la base 6-311 G (d, p) (reaction 1) et d'autre part celle qui correspond a l'interaction entre le dichloroacetate d'isopropyle et le dialdogalactose (serie glucidique) en utilisant la base 6-31 G (d) (reaction 2). En ce qui concerne la premiere reaction, nous avons observe que: les geometries correspondantes aux reactifs et aux produits sont plus stables dans le solvant que dans la phase gazeuse, le dihalogenoacetate d'isopropyle a un comportement nucleophile alors que l'isobutyraldehyde a un comportement electrophile. L'attaque locale a eu lieu entre le carbone du dihalogenoacetate d'isopropyle et le carbonyle d'isobutyraldehyde, l'attaque locale est plus privilegiee dans le solvant que dans le gaz.
