CH3CN and O2 do the trick! A copper‐mediateddirectoxidativecross‐coupling of 2‐(het)aryl‐1,3,4‐oxadiazoles with polyhaloarenes under mild reaction conditions has been developed (see scheme). The process provides a concise access to biaryl structures containing polyhaloarenes, which are of interest in the fields of pharmaceuticals and functional materials. Acetonitrile and oxygen play crucial roles
