TECHNICAL DESCRIPTION

The invention concerns polydentate phosphines ligands that form in particular metal complexes and supported catalysts. It concerns also synthesis processes of these components, complexes and supported catalysts as well as intermediar products used in these processes. It concerns also the use of these components. The components of the invention are phosphine-functionnalized ferrocenic components to be supported, which give heterogeneously usable ligands. The invention finds application in the recycling and sustainable metal-catalyzed cross-coupling catalysis in particular.
