A Rh(I) diphosphine complex was anchored on an activated carbon by means of a covalent bond and tested as catalyst for the hydroformylation of 1-octene. The heterogenization procedure included the functionalization of the carbon surface to create acid chloride groups where an esterification reaction with the hydroxyl end of a diphosphine ligand (HONP) could take place. Two strategies were followed, i.e., route 1, ligand anchorage followed by complex formation (using the [Rh(μ-Cl)(COD)]2 complex as precursor) and route II, synthesis of the rhodium diphosphine complex [Rh(HONP)(COD)]Cl followed by anchorage on the functionalized carbon support. The two synthetic routes rendered catalysts that were active, selective, and stable enough to be used in consecutive catalytic runs. The anchoring procedure that first synthesized the Rh diphosphine catalyst and then bonded it to the carbon surface, was particularly attractive: the resulting catalyst is fully active in four consecutive catalytic cycles with a conversion to the linear aldehyde that increased with reuse.
