Abstract The hydroformylation of highly substituted alkyl olefins was efficiently performed, with use of rhodium(I)/tris-binaphthyl monophosphite catalysts, containing different ether substituents at the 2′-binaphthyl position (OMe, OBn, OCHPh 2 and OAdamantyl). A systematic kinetic study, carried out for hydroformylation of methyl non-3-enoate, has shown a significant influence of the ligand’s OR group
