Cheap and air stable copper(I) iodide can now be used as catalyst for arylation of sp2 C-H bonds. A combination of copper(I) catalyst and a base such as potassium or lithium t-butoxide or potassium phosphate can replace expensive Pd catalysts in some C-H activation processes. This protocol was found to be effective for arylation of electron-rich and electron-poor heterocycles, polyfluorobenzenes and ketones.
