The palladium/copper-cocatalyzed oxidative C-H/C-H cross-coupling between two heteroarenes by using molecular oxygen as an oxidant instead of metal oxidants has been developed for the first time to construct biheteroaryl motifs. A relatively broad range of thiophenes, furans and indoles can smoothly couple with various N-heteroarenes in satisfactory yields. This catalytic system with O2 as the terminal oxidant offers clear advantages of economically feasible and eco-friendly processes.
