Transition-Metal-Catalyzed C-H Functionalization of Heterocycles, 2 VolumesA comprehensive guide to recent advances in this field Constituting the majority of all known compounds, heterocycles are structures that incorporate one or more heteroatoms within their core, thus exhibiting properties that are quite different from their all carbon analogs. They are fundamental to all fields of chemistry and, therefore, their synthesis and modification has attracted a great deal of attention in the recent years. In this vein,
