The cationic gold phosphine complex [(o-biphenylPCy2)Au(NCMe)]+ SbF6− catalyzes the intermolecular, anti-Markovnikov hydroamination of methylenecyclopropanes (MCPs) with 2-pyridones at 80 °C. The transformation was effective for a range of pyridones and for monosubstituted and cis- and trans-disubstituted MCPs to form 1-cyclopropylmethyl-2-pyridones with excellent regio- and diastereoselectivity in
