Description

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.

BENEFITS

Permit to multiply by 3 to 4 the local density of coordinating atoms on almost any kind of support (inorganic, organic, silica, mesoporous materials, polymers) without increasing the initial ligand charge (usable for stabilization and life span of catalytic systems). Air-stable, moisture insensitive, thermally stable (until 150°C) ligands. 

INDUSTRIAL APPLICATIONS

Heterogeneous catalysis with recycling objective in the following reactions, palladium and/or copper-catalyzed reactions: carbon-carbon bond formation (Suzuki, Heck, Sonogashira), carbon-heteroatom formation (Buchwald-Hartwig amination/etheration, Tsuji-Trost, allylation), heterocycles functionalization (furans, thiophenes, pyrazoles, pyridine, thiazole, pyrimidine, etc.) by direct C-H and/or C-Cl, C-Br activation.
