Rhodium phosphine complexes immobilized on silica as active catalysts for 1-hexene hydroformylation and arene hydrogenation

Rhodium phosphine complexes immobilized on silica as active catalysts were successfully tested with respect to their catalytic action on 1-hexene hydroformylation as well as benzene and toluene hydrogenation. The reaction outcome, i.e., the formation of aldehydes vs. isomerization, depended strongly on the presence and concentration of a phosphine co-catalyst. During immobilization, Hacac was completely removed after protonation by silica proton. In the presence of an excess of phosphinated silica P-{SiO2}, the yield of aldehyde increased with concomitant suppression of the isomerization. The pre-catalyst [Rh(O-{SiO2}(HO-{SiO2})(CO)(P-{SiO 2})] (1a) was more active both in hydroformylation and in isomerization of 1-hexene compared with [Rh(O-{SiO2})(HO-{SiO2})(P-{SiO 2})2]. Additionally, 1a catalyzed hydrogenation of aromatic hydrocarbons (benzene and toluene).
