摘要

The present review reports on the chemistry of the osmium-carbon double bond, including alkylidene or carbene, vinylidene, and allenylidene derivatives. Within the first type of compounds, we show the synthetic methods and reactivity of half-sandwich derivatives, including cyclopentadienyl and arene complexes, carbene compounds derived from alkynes, α,β-unsaturated carbene species, and osmacyclopropene, hydride-carbene, osmafurane, and osmapyrrole complexes. The vinylidene compounds include: half-sandwich, PCP "pincer", hydride-vinylidene, azavinylidene-vinylidene, and metallaarene derivatives. For their study the allenylidene complexes have been divided into half-sandwich and non-half-sandwich compounds. In addition, the transformation from hydride-carbyne to carbene is analyzed, the preparation of butadienyl compounds via vinylidene intermediates is shown, and the assembly of organic molecules on allenylidene species to form osmacyclopentapyrrole derivatives is described.
