The discovery of an ultrafast cross‐coupling of alkyl‐ and aryllithium reagents with a range of aryl bromides is presented. The essential role of molecular oxygen to form the active palladium catalyst was established; palladium nanoparticles that are highly active in cross‐coupling reactions with reaction times ranging from 5 s to 5 min are thus generated in situ. High selectivities were observed for
