Abstract Herein, employing pincer like cobalt (II) complexes containing redox noninnocent azo‐benzimidazole ligand a switchable and chemodivergent catalytic cross‐coupling of primary secondary alcohols is reported. The reactions are environmentally benign atom efficient. It liberates water hydrogen gas as the only byproducts. While reaction in inert condition gives alkylated ketones, presence air well lower temperature base loading selectively results unsaturated ketones. Both protocols have very good functional group tolerance. Thus, wide range substrates been found to be effective for synthesis ketones via dehydrogenative alcohols. Several control experiments kinetic studies were performed elucidate pathways.
