Thioether-phosphite ligands (S)-BINOL-PO(CH2)nSPh (SP’s, n = 2, 3; BINOL-H2 = 1,1′-binaphthyl-2,2′-diol, H8-1,1′-binaphthyl-2,2′-diol) with axially chiral binaphthyl or 5,5′,6,6′,7,7′,8,8′-octahydrobinaphthyl moiety and their [Rh(COD)(SP)]BF4 complexes have been synthesized to study their coordination chem. and catalytic features and to compare them to those of the structurally analogous phosphine-phosphites (S)-BINOL-PO(CH2)nPPh2 (PP’s). NMR exchange studies on [Rh(COD)(SP)]BF4 complexes showed selective 1,5-cyclooctadiene dynamics. Firm evidence has been found that this fluxional process involves dissociation of the Rh-sulfur bond. Based on in situ NMR studies, SP ligands can form two types of bis-ligated species at ligand-to-metal ratio higher than 1. Unlike bis-ligated phosphine-phosphite complexes, bis-ligated thioether-phosphite Rh-complexes can efficiently catalyze asym. hydrogenation reactions due to their distinct coordination chem.
