  • Title: Catalytic alkene cyclohydroamination via an imido mechanism.
    Author: Gott AL, Clarke AJ, Clarkson GJ, Scott P.
    Journal: Chem Commun (Camb); 2008 Mar 28; (12):1422-4. PubMed ID: 18338043.
    Abstract:
    Chiral-at-metal half-sandwich diamide complexes catalyse enantioselective cyclohydroamination of aminoalkenes at unexpectedly high rates given their high coordination number and steric bulk; substantial evidence is presented which argues against the established sigma-bond insertion process and is strongly indicative of an imido [2+2] cycloaddition mechanism.
