phosphorusligandmodifiedrhsio2catalystforhydroformylationofmethyl3pentenoate

Abstract

A phosphorus ligand-modified Rh/SiO2 catalyst (L-Rh/SiO2) has been developed for hydroformylaiion of internal olefins to linear aldehydes. This catalyst has high activity and regioselectivity and can be separated easily by filtration after reaction in an autoclave. Moreover, the electronic and steric effects of phosphorus ligands on the catalytic performance of the L-Rh/SiO2 catalyst have been investigated by using various monodentate and chelating diphosphorus ligands
