In the last decades, CH activation became an increasingly powerful tool for CC bond formation. It provided a valid alternative to conventional cross coupling reactions with maximised atom- and step-economy for synthetic reactions. Even though a lot of great advances have been made, some challenges in CH activations remain. CH bonds are highly stable (110 kcal/mol), often harsh reaction conditions are needed to break the bond and form a new CC compound. Furthermore, regioselectivity has been proven to be a difficult issue since a number of CH bonds are present in organic molecules. Also, chemoselectivity still remains a difficulty to overcome in CH activation reactions. Many groups focus their research on developing mild reaction conditions that proceed at ambient temperature, neutral conditions and in absence of strong oxidants or reductants.[1b] By choosing milder reaction conditions also problems of selectivity can be managed. In general, the catalytic cycle of CH activation react
