Formation of arylnitrogen bonds using a soluble copper(I) catalyst

We report a synthetic protocol for the synthesis of functionalized diaryl- and triarylamines under mild conditions, using a soluble, air-stable copper(I) complex, Cu(PPh3)3Br, as the catalyst and cesium carbonate as the base. Using this protocol, we were able to synthesize a tri-ortho-ester functionalized triphenylamine, which had eluded us using the palladium chemistry.
