The activation of C-H bonds represents a complex and paradigm-shifting chemical process where C-H bonds embedded in organic molecules undergo both cleavage and functionalization. These bonds are classified as chemically inactive due to their high bond dissociation energy and non-reactive functional groups, hence they are often difficult to modify in synthetic chemistry. This process makes it possible to convert C-H bonds into many useful functional groups; these include carbon-carbon (C-C), carbon-nitrogen (C-N), carbon bonded to oxygen (C–O), and others. There is no need therefore to have pre-functionalized starting materials which is a requirement for most traditional synthetic methods. This straightforward approach not only streamlines reaction sequences and decreases the number of operations involved in synthesis, but also cuts down the volume of waste by removing the need to produce undesired by-products.

The field of C-H activation has experienced great interest because of its ability to potentially accelerate the synthesis of, for example, complex molecules, drugs, natural substances, and materials. It is atom efficient and environmentally friendly, thus contributing in favor of the tenets of green chemistry, which means it is more and more viable both in academic and industrial activities.
C-H activation reactions can be designed to improve selectivity and sustainability in modern synthetic chemistry.

Innovative Methodologies
To maximize C-H activation, it is essential to have effective design and planning even at the very beginning of the process.
Catalysts are composed of Transition metals, Palladium, and Ruthenium along with N-heterocyclic carbenes, which work together to enhance the desired working parameters.
Further optimizations can be done using group-directing methods such as ketones or amides which can improve and enhance the selectivity of the reactions.
Environment-friendly methods such as photo- and electrocatalysis can be used to expand the green C-H reaction.
