developed, which allows for easy access to 1,4-difunctionalised compounds which are not otherwise readilyaccessible. Crucially, a more general acceptor substrate scope is now possible, which renders the Giese amidation applicable to more complex substrates such as natural products and chiralbuildingblocks. Two different photocatalytic methods (one via oxidative and the other via reductive quenching

A direct method for C–H dicarbamoylations of phenanthrolines has been developed, which is capable of directly installing primary, secondary as well as tertiary amides. This is a significant improvement on the previous direct method, which was limited to primary amides. The metal-, light-, and catalyst-free Minisci-type reaction is cheap, operationally simple, and scalable. We demonstrate that the step
