Gladiali, Serafino published the artcileNovel heterobidentate ligands for asymmetric catalysis: synthesis and rhodium-catalyzed reactions of S-alkyl (R)-2-diphenylphosphino-1,1′-binaphthyl-2′-thiol, SDS of cas: 126613-06-7, the publication is Tetrahedron: Asymmetry (1994), 5(7), 1143-6, database is CAplus.
Atropisomerically pure (R)-2-diphenylphosphino-1,1′-binaphthyl-2′-thiol (I) S-alkyl derivatives have been synthesized through a multistep reaction sequence starting from (R)-binaphthol. Pd(II) and Rh(I) complexes containing the I S-Me derivative as a chelate ligand have been prepared and characterized. Rh(I) complexes containing the I S-Me or the I S-iso-Pr derivative effectively catalyze the asym. hydroformylation of styrene and the hydrogen transfer reduction of acetophenone.
