Abstract
L'invention concerne un procédé amélioré de préparation de 3,5,5-triméthylcyclohex-2-ène-1,4-dione par oxydation de 3,5,5-triméthylcyclohex-3-èn-1-one en présence d'un agent d'oxydation et d'un système de catalyse comprenant un complexe de métaux de transition en tant que catalyseur, une base auxiliaire, éventuellement de l'eau et un co-additif actif du point de vue catalytique. Ce procédé est caractérisé en ce que des amides d'acide carboxylique sont employés en tant que solvant.
