Abstract
The effect of ancillary phosphine ligands on the structure and hydroformylation activity of Rh-N-heterocyclic carbene complexes of type [Rh(IMes)(PR3)(CO)Cl] and [Rh(SIMes)(PR3)(CO)Cl] is described. Very high selectivities for the branched isomer (>95:5) were obtained in the hydroformylation of vinylarenes in all cases except for R = OPh. The new complexes were characterized spectroscopically and by X-ray crystallography.Key words: hydroformylation, rhodium, N-heterocyclic carbene, IMes.
