C-H activation is a field of research in organic chemistry that focuses on developing methods to selectively activate C-H bonds in organic molecules. This process involves breaking the strong bond between a carbon atom and a hydrogen atom in order to create new bonds and functional groups. C-H activation has emerged as an important tool in organic synthesis, allowing chemists to streamline the construction of complex molecules by directly functionalizing C-H bonds rather than relying on traditional methods that often involve multiple steps and functional group transformations. This area of research has led to the development of new synthetic methodologies and strategies for the efficient and selective modification of organic compounds.
