Carbon ylides and disylides. Coordination chemistry on carbon atoms

Abstract

This article introduces an alternative view to ylide nature that allows the definition of carbon ylides. Their physical and chemical properties, as well as the attempts directed to the synthesis of carbon bisylides are also reviewed. The highly non canonical bonding situation in such compounds forces an interpretation as coordination compounds, in which carbon serves as a central atom that interacts with its ligand sphere via donor-acceptor bonds.
