Abstract
This review presents synthetic procedures applied to the preparation of chiral (mainly optically active) hypervalent chalcogenuranes. The stereoisomerization mechanisms of hypervalent derivatives of sulfur, selenium and tellurium and their selected interconversions are also presented.
Keywords: Hypervalency, chirality, sulfurane, selenurane, tellurane, Berry pseudorotation, turnstile rotation.

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
