Access to enantioenriched 1,2-disubstituted allylic fluorides in good to high levels of enantiomeric excess was achieved using a chiral diene-ligated rhodium catalyst. Experimental results together with DFT calculations support a dynamic kinetic asymmetric transformation process, whose efficiency is impacted by developing steric interactions in the syn and anti π-allyl intermediate complexes.
