materials, and there has been a growing interest in new synthetic methods for their preparation. In this paper, we report a direct cross-coupling reaction of heteroarenes with N,N-dimethylanilines in the presence of copper catalyst. Oxygen and/or air are successfully used as the oxidant, which is of great importance to the industrialized economies. The reaction is compatible with a wide range of heterocycles

A one-pot dual functionalization of indoles has been developed. The simultaneous C3-formylation and N-aminomethylation of indoles can be achieved using readily available potassium iodide as a catalyst and tert-butyl peroxybenzoate as a co-oxidant.
