Using Co­(PMe<sub>3</sub>)<sub>4</sub> as catalyst we have developed an efficient and simple protocol for the C–H/hydroarylation of alkynes with an <i>anti</i> selectivity. Deuterium-labeling experiments, DFT calculations coupled with the use of a well-defined catalyst have for the first time shed light on the elusive black box of cobalt catalyzed C–H functionalization. 2015-02-25 00:00:00 cobalt functionalization DFT calculations catalyst
