Catalytic hydroformylation in the presence of rhodium complexes with homo- and heterocombination of two monodentate P-ligands

Activity of the complex containing both a phosphine and an amidophosphite ligand in the coordination sphere of rhodium was determined for the first time in the hydroformylation of styrene and oct-1-ene in supercritical carbon dioxide and benzene. The efficiency of this “mixed” heteroligand complex was compared with that of its analogs each containing the same two phosphine or two amidophosphite ligands.
