“…[53][54][55][56] These molecules are structurally quite similar to 43-45. It is interesting to note that the authors did not report these complexes as aromatic, though they do have some characteristics suggesting that delocalization is present.…”

Research into aromatic metallacycles, though discussed in the literature over the last quarter century, has undergone a major expansion since 2000. A wide variety of new metallabenzenes, encompassing new synthetic methods and new metal centers, is now available. New aromatic metallacycle topologies (iridanaphthalene, osmabenzynes) have been isolated and characterized. The first metallabenzene valence isomers (iridabenzvalenes, rhodabenzvalenes) and constitutional isomers (isoosmabenzenes) are now known. This review discusses the synthesis, chemistry, and physical properties of these intriguing aromatic compounds.

“…Although examples of these compounds are still relatively rare as well, the large possible number of variationsi nr ing size, heteroatom choice, degree of saturation and substitution (as well as possible isomers) suggests this could potentially developi nto av ery large set of compounds. Compounds in this class that have already been reported [117] include metallabenzothiirenes, [37,46,78] metallabenzoxirenes, [59,129] metallabenzazirines [59] metallabenzofurans, [91,[130][131][132][133][134] metallabenzothiophenes, [73,135] metallabenzothiazole, [52] metallabenzothiazolium, [78] and metallabenzoxathioles.

Metallaaromatics can be broadly defined as aromatic compounds in which one of the ring atoms is a transition metal. The metallabenzenes are one important class of these compounds that has undergone extensive study recently. Closely related species such as fused-ring metallabenzenes, heterometallabenzenes, π-coordinated metallabenzenes and metallabenzynes have also attracted considerable attention. Although many metallaaromatics can be considered as metalla-analogues of classic organic aromatic compounds, this is not always the case. Recent seminal studies have shown that metallapentalenes and metallapentalynes, which are metalla-analogues of the anti-aromatic compounds pentalene and pentalyne, are in fact aromatic and highly stable. Very unusual spiro-metallaaromatic compounds have also recently been isolated. In this concepts article, key features of all these intriguing metallaaromatic compounds are discussed with reference to the structural, spectroscopic, reactivity and theoretical studies that have been undertaken. These compounds continue to generate much interest, not only because of the contributions they make to fundamental chemical understanding, but also because of the promise of possible practical applications.

“…The CCCO moieties are alkynyl ketones (RCCCOR′), alkynyl esters (RCCCOOR′), alkynyl diesters (ROOCCCCOOR′), etc. The metal atoms of the metal compounds such as Mn, Re, Fe, Ru, Os, Rh, Ir, Ni, Pd and Pt are used for these cyclization reactions 84–113. In the CCCO moiety, the metal is coordinated at two coordination sites: the alkynyl π‐electron bond and the carbonyl oxygen atom.…”

Carbonyl group-containing organometallic intramolecular-coordination five-membered ring compounds are easily synthesized by the following five reaction methods: (1) cyclometalation, especially, orthometalation reactions; (2) the reactions of the moieties of an unsaturated carbon-carbon bond attached to a carbonyl group (C C-CO, C C-CO); (3) the reactions of an unsaturated carbon-carbon bond with carbon monoxide (C C and CO, C C and CO); (4) carbonylative ring expansion reactions; and (5) others. These compounds are very easily and regio-specifically synthesized with many kinds of metal compounds, including both transition metals and main group metals. Many of such the reactions are easily applied to organic syntheses.
