Catalysis using earth-abundant transition metal complexes has attracted considerable attention in organic synthesis. This presentation will highlight our studies on the development of novel synthetic transformations promoted by low-valent cobalt catalysts. Our group has demonstrated the ability of low-valent cobalt catalysts to promote a series of C–H activation/functionalization reactions such as hydroarylation of alkynes/alkenes, C–H/electrophile coupling, arylzincation via 1,4-cobalt migration, and hydroacylation, a part of which will be discussed here. These studies have also prompted us to explore the scope of low-valent cobalt catalysts beyond C–H activation, and some of the results of such exploration will also be presented.
