The next sections will discuss in more detail different dehydrogenation reactions performed in organic synthesis (see Table 1 for a summary). These reactions have been chosen to exemplify the complex reaction conditions and catalyst formulation associated with different reaetants. 

Despite the encouraging results discussed in this chapter, we must admit that the field of asymmetric C—H bond functionalization reactions through a transient C—M species is still in its infancy. Most of the existing reactions suffer from drawbacks such as narrow substrate scope, low catalytic efficiency and complex reaction conditions. In addition, the current methodologies are mainly restricted to the utilization of some certain activated C—H bonds and in most of the successful examples the complexes of noble metals (Pd, Rh, Ir, etc.) are utilized as the catalysts. Therefore, to develop novel asymmetric C—H bond functionalization reactions that (1) involve more inert C—H bonds or (2) employ cheap metal (Cu, Fe, Co, Ni, etc.) complexes as the catalysts should be of great importance.
