The asymmetric hydroformylation of allylbenzenes and propenylbenzenes is an important tool for obtaining high value intermediates for the pharmaceutical and perfume industry. We have studied these reactions with rhodium-chiral diphosphite systems. The diphosphite ligands 6 and 7 with carbohydrate backbone have high regioselectivities in trans-anethole hydroformylation and moderate ones in estragole hydroformylation. Only low enantioselectivities have been observed in the trans-anethole hydroformylation with the diphosphite 6 based system.
