In contrast to the rapid growth of synthetic electrochemistry in recent years, enantioselectivecatalytic methods powered by electricity remain rare. In this work, we report the development of a highly enantioselective method for the electrochemical cyanophosphinoylation of vinylarenes. A new family of serine-derived chiral bisoxazolines with ancillary coordination sites were identified as optimal
A process for preparing an allyl ether including reacting (a) a phenolic compound with (b) an allyl carboxylate or an allyl carbonate in the presence of (c) a transition metal or rare earth metal catalyst complexed with at least one strongly bonded, non-replaceable stable ligand whereby an allyl ether is formed. The ligand of the transition metal or rare earth metal catalyst complex may be (i) an olefinic-containing ligand or aromatic-containing ligand; or (ii) a polymeric ligand or a heteroatom-containing multidentate ligand.
