An operationally simple cross-coupling reaction between aryl halides and alkyl halides with high selectivity utilizes CoCl2/Me4-DACH as a catalyst system. The underlying domino process exhibits high sustainability as it obviates the need for the pre-formation and handling of stoichiometric amounts of hazardous Grignard compounds.
