Over the last decades, transition-metal-catalyzed C-H activation has emerged as a powerful tool for the construction of carbon–carbon bonds. Until recently, the majority of these transformations were achieved employing precious second- and third-row transition metals. However, the development of novel methodologies based on more cost-effective first-row transition metal complexes has emerged as a very attractive alternative. Among them, cobalt catalysis has shown its potential to construct C-C bonds. Despite this significant progress, these Co systems are still at their infancy and important, fundamental questions remain unsolved, specially concerning the lack of information on the mechanisms of these transformations. We have performed a detailed mechanistic investigation of Co-mediated C-H activation using model substrates to explore the different elementary steps involved in these transformations.
