This article provides an overview on the aromatic systems of four-membered rings. These aromatic four-membered ring systems are rather exotic because of a poor correspondence between the Huckel rule and the structure of four-membered rings. Consequently, such aromatics are generally dications or dianions, to form 2 pi or 6 pi electron systems respectively. Alternatively, the use of open-shell structures or empty d-orbitals of transition metal atoms could give neutral aromatic four-membered ring systems. This paper summarizes the four-membered aromatic compounds reported to date and describes the various methods for evaluating their aromaticity.
