Aryl(triethyl)silanes are found to undergo cross‐coupling with iodoarenes in the presence of catalytic amounts of CuBr2 and Ph‐Davephos, as well as cesium fluoride as a stoichiometric base. Because the silicon reagents are readily accessible through catalytic C−H silylation of aromatic substrates, the net transformation allows coupling of aromatic hydrocarbons with iodoarenes via triethylsilylation
