Abstract
Halogen dance (HD) reaction is an important tool in modern organic chemistry. This reaction is defined as halogen migration induced by bases, normally in aromatic and heteroaromatic systems. It is successfully applied in aromatic and different classes of heteroaromatic compounds, such as thiophene, quinoline, pyridine, thiazole, and many others. Due to the importance of this reaction, the aim of this review is to discuss the HD reaction and its application in organic synthesis between 1992-2005.

Catalytic C-H bond activation as a tool for functionalization of heterocycles
The major topic is the functionalization of heterocycles through catalyzed C-H bond activation. The strategies based on C-H activation not only provide straightforward formation of C-C or C-X bonds but, more importantly, allow for the avoidance of pre-functionalization of one or two of the cross-coupling partners. The beneficial impact of ...read more
