Oxidative Imidation of Benzylic and Cycloalkane C(sp3)–H Bond Donors Using N-Aroyloxyquinuclidinium Salts and Nitriles under Photoredox Catalysis

A series of N-aroyloxyquinuclidinium salts were prepared and used as reagents to perform efficient three-component Ritter–Mumm-type oxidative C–H imidation of donors of 1° and 2° benzylic C–H bonds used as limiting reagents with nitriles as a source of imide nitrogen under photocatalytic conditions; these reagents also exhibit somewhat lower reactivity toward cycloalkanes.
