Immobilization of an Anthracene-Tagged Ruthenium Complex on a 2,4,7-Trinitrofluoren-9-one-Grafted Silica: Efficiency and Recyclability in Olefin Metathesis Reactions
Résumé
An anthracene group was linked to the N-heterocyclic carbene moiety of a M71-SIPr-type Ru complex. The tagged complex thus obtained was immobilized by charge-transfer interactions to a 2,4,7-trinitrofluoren-9-one-grafted passivated silica. The immobilized complex proved to be an efficient olefin metathesis catalyst and was reused five times in a multisubstrate olefin metathesis procedure.
