    NHC-Mediated Chlorination of Unsymmetrical Ketenes: Catalysis and Asymmetry

    No full text
    NHCs promote the efficient chlorination of unsymmetrical disubstituted ketenes with a range of chlorinating agents; chiral NHCs display promising levels of asymmetric induction in the chlorination process with up to 61 % ee observed using 2,3,4,5,6,6-hexachlorocyclohexa-2,4-dienone.</p
