Abstract

Abstract Translated from French Systèmes catalytiques perfectionnés à longue durée de vie, comprenant initialement : (a) un composé du tungstène ; (b) un composé organométallique, (c) un composé organique partiellement ou totalement fluoré. Procédé de stabilisation de ces systèmes catalytiques, comprenant la mise en solution de (a) dans un solvant organique, la mise en contact de (b) avec (a), l'agitation et le chauffage entre 0° et 100°C pendant 0,5 à 60 minutes, puis introduction de (c) dans le mélange de (a) et (b). Application de ces systèmes catalytiques stabilisés à la métathèse d'oléfines portant des groupes fonctionnels ou ne portant pas de tels groupes. Advanced long-life catalytic systems, initially comprising: (a) a tungsten compound; (b) an organometallic compound, (c) an organic compound partially or totally fluorinated. Method for stabilizing these catalytic systems, comprising dissolving (a) in an organic solvent, bringing (b) into contact with (a), stirring and heating between 0 ° and 100 ° C for 0 , 5 to 60 minutes, then introduction of (c) into the mixture of (a) and (b). Application of these stabilized catalytic systems to the metathesis of olefins carrying functional groups or not carrying such groups.
