Abstract
Cycloaddition and cycloisomerization reactions involving alkynes grant a rapid access to arenes, cyclic dienes, and cyclopentenone derivatives. The use of alkynes substituted by group 13 or 14 heteroelements as partners for such reactions is an emerging strategy. Indeed, the specific electronic properties of these heteroelements can play a crucial role for controlling the chemo- and regioselective outcome of a given reaction. Moreover, the heteroatoms can be considered as latent functional groups and would allow for further transformations including Suzuki-Miyaura or Stille crosscouplings. Both aspects will be presented in this review.

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
