Recent Developments in the Chemistry of NHC-based Selones: Syntheses, Applications and Reactivity.

Selones, since their first report in 1963, have attracted significant interest with respect to their bonding, structure and more importantly as an ancillary ligand for complexation with various metals. Starting as an analogue of N-heterocyclic carbene (NHC), selones are considered as promising molecules in chemistry with numerous applications in various important processes. Herein, a brief overview of selone, its genesis and relevance in contemporary chemistry is given, particularly focusing on its syntheses, reactivity and applications. [ABSTRACT FROM AUTHOR]
