3,3'-Disubstituted xylBINAP derivatives were applied to inter- and intramolecular asymmetric Heck/Mizoroki reactions. The results from these reactions were compared to those obtained with (R)-xylBINAP, (S)-BINAP and 3,3'-disubstituted BINAP derivatives. Catalysts derived from 3,3'-disubstituted xylBINAP ligands were found to be most effective in the arylation of 2,3-dihydrofuran in terms of reaction times, conversions, and product enantioselectivity.
