Mizoroki-Heck reaction, which couples arylhalides with olefins, has been widely used to stitch together the carbogenic cores of numerous complex organic molecules. Given that the position-selective introduction of a halide onto an arene is not always straightforward, direct olefination of aryl carbon-hydrogen (C–H) bonds would obviate the inefficiencies associated with generating halide precursors or
