Carbon–hydrogen bond activation
Chemists study C-H activation because for many years chemists believed that C-H bonds were unreactive.  Both theoretical studies as well as experiments now show that C-H bonds can be broken. This is done by a nearby metal atom changing the electron distribution of the C-H bond (coordination).  Much chemical research looks at the design and synthesis of new reagents and catalysts that can affect C-H activation.  The goal of this research is the conversion of cheap and abundant alkanes into valuable functionalized organic compounds.
