Asymmetric hydroformylation with highly crosslinked polystyrene-supported (R,S)-BINAPHOS-Rh(I) complexes: the effect of immobilization position.
A new class of polymer-supported (R,S)-BINAPHOS 1e in which the parent BINAPHOS has two alkoxy-substituents at the 3-positions of the phenyls, has been synthesised. Using its Rh(I) complex, asymmetric hydroformylation of olefins proceeded with higher enantioselectivity in some cases compared to the conventional polymer-supported 1c.
