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...

Activation and selective oxy-functionalization of alkanes with metal complexes: Shilov reaction and some new aspects
