Abstract:
A photo- and dioxygen-enabled intermolecular radical Csp-Nsp cross-coupling between guanidines and perfluoroalkyl iodides has been developed. N2-Perfluoroalkacylguanidines, which are of biological importance, were obtained under mild conditions via Nsp-perfluoroalkylation and subsequent hydrolysis. The role of dioxygen in the reaction system was tentatively elucidated; it was supposed to act as an electron shuttle (redox mediator).

Palladium-Catalyzed Cross Coupling
This experiment will demonstrate the concept of a palladium-catalyzed cross coupling. The set-up of a typical Pd-catalyzed cross coupling reaction will be illustrated. Pd-catalyzed cross coupling reactions have had a profound effect on how synthetic chemists create molecules. These reactions have enabled chemists to construct bonds in new and more efficient ways. Such reactions have found widespread...
