The rising demand and financial costs of noble transition metal catalysts have emphasized the need for sustainable catalytic approaches. Over the past few years, base-metal catalysts have emerged as ideal candidates to replace their noble-metal counterparts because of their abundance and ease of handling. Despite greater than 60 years of significant advancements in areas of allylic coupling using precious transition metals, earth-abundant cobalt catalysts have only recently been reported as alternatives for allylic substitution reactions. The review article highlighted here describes the state-of-the-art for allylic alkylations at sp3-carbon centers mediated by cobalt. The design strategies for allylic coupling of C3+ units reveal classical approaches as well as modern photoredox methods. Finally, the current mechanistic understanding of these underdeveloped reactions is discussed along with outstanding mechanistic questions.
