Enantiopure platinum(II) complexes with chiral diphosphine and diphosphinite ligands derived from 2,2-biphosphole: Synthesis, crystal structure and catalysis

Enantiopure platinum(II) complexes have been synthetized with chiral stereodynamic diphosphine and diphosphinite ligands derived from 2,2-biphosphole through a dynamic chirality control upon coordination. Catalytic performances of these platinum complexes have been explored in asymmetric hydroformylation. All complexes proved to be effective catalysts with respect to chemoselectivity and regioselectivity but induced only low enantioselectivities.
