Metal-catalyzed CH activation/functionalization: The fundamentals 10.1016/j.molcata.2016.06.020 2016-09-04 An isolated CH bond in a molecule has a very low reactivity owing to the large kinetic barrier associated to the CH bond cleavage and the apolar nature of this bond. For this reason, the selective reactivity of such a non-functional group is under active stud...
