Immobilization of an Anthracene-Tagged Ruthenium Complex on a 2,4,7-Trinitrofluoren-9-one-Grafted Silica: Efficiency and Recyclability in Olefin Metathesis Reactions

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 met...

Description
Summary: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. An anthracene group is linked to the N‐heterocyclic carbene moiety of a M71‐SIPr‐type Ru complex. The tagged complex thus obtained is immobilized by charge‐transfer interactions to a 2,4,7‐trinitrofluoren‐9‐one‐grafted passivated silica. The immobilized complex is an efficient olefin metathesis catalyst and can be reused five times in a multisubstrate olefin metathesis procedure.
