Rhodium-containing hypercross-linked polystyrene as a heterogeneous catalyst for the hydrofonmylation of olefins in supercritical carbon dioxide

A simple procedure for the incorporation of rhodium nanoparticles into a hypercross-linked polystyrene matrix is developed. The prepared heterogeneous catalyst shows high activity in the hydroformylation of olefins in supercritical carbon dioxide, and can be recycled six times without any noticeable decrease in productivity.
