Abstract
The review article covers the hypervalent organoantimony compounds that are with intramolecular N, O, S→Sb coordinations synthesized in the past 20 years. We describe their structures and the related coordination chemistry, highlighting a number of hypervalent stibines. These compounds have shown many applications in organic synthesis. They are useful reagents for reactions such as crosscoupling and arylation with organic halides, and addition with carbonyl compounds. They can be used as Lewis acid catalysts in organic synthesis. Furthermore, they can be utilized as catalysts or reagents for CO2 chemical fixation. It is envisaged that more hypervalent organoantimony compounds of novel structure will be synthesized and find new applications in the near future.
Keywords: Organoantimony, Hypervalent compounds, Intramolecular coordination, Organic synthesis, Structure, Reagent, Catalyst, dimethylaminopiridine, triarylstibines, aromatic substituent, (N, N-dimethylamino)ethylferrocene.

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
