the addition of alkalimetal salts to styrene hydroformylation reactions catalyzed by Rh(I) complexes of bis(phosphite) ligands can significantly improve the iso/n regioselectivity. To better understand the effects of the alkalimetal salts on these styrene hydroformylation reactions, a monodentate phosphite–ether ligand, (2,2′-C12H8O2)POCH2CH2OCH3, 1 has been prepared, and its Rh(I) complex has been
