A Highly Asymmetric Gold(III) η3‐Allyl Complex

A highly asymmetric AuIII η3‐allyl complex has been generated by treating Au(η1‐allyl)Br(tpy) (tpy=2‐(p‐tolyl)pyridine) with AgNTf2. The resulting η3‐allyl complex has been characterized by NMR spectroscopy and X‐ray crystallography. DFT calculations and variable temperature 1H NMR suggest that the...

Description
Summary:A highly asymmetric AuIII η3‐allyl complex has been generated by treating Au(η1‐allyl)Br(tpy) (tpy=2‐(p‐tolyl)pyridine) with AgNTf2. The resulting η3‐allyl complex has been characterized by NMR spectroscopy and X‐ray crystallography. DFT calculations and variable temperature 1H NMR suggest that the allyl ligand is highly fluxional. Gold and dynamic: The π coordination of an allyl group at the cyclometalated (N,C coordinated) AuIII moiety induces high asymmetry in the allyl group. DFT calculations and variable temperature 1H NMR spectroscopy suggest that the allyl ligand is highly fluxional.
