Fecha de publicación: | 2020 | Editor: | Elsevier | Citación: | Advances in Organometallic Chemistry 74: 53-104 (2020) | Resumen: | Unsaturated osmium(IV)-hydride complexes are diamagnetic six-coordinate d4 species, which undergo distortion from the octahedral geometry to form unusual D4d or C2v geometries. They display a notable ability to activate HH, BH, CH, CC, CO, CBr, SiH, SnH, NH, or OH bonds of a wide range of inorganic, organic, and organometallic molecules, including: molecular hydrogen, boranes, phosphines, heterocycles, olefins, dienes, enynes, allenes, allenedienes, alkynamides, alkylhalides, silanes, stannanes, diamines, oximes, metal-nucleosides, or molecular oxygen. The activations yield, among other organometallic derivatives, dihydrogen, borane, borinium, alkylidene, alkylidyne, vinylidene, NHC, silylene, stannyl, osmafuran, osmaisobenzofuran, osmabenzimidazolium, or azavinylidene complexes. A characteristic of these activation processes is that they do not result in an increase of the formal oxidation state of the metal center. Given the wide range of σ-bond activations promoted by these compounds and the wide variety of complexes formed, future interesting applications for them can be anticipated. | Descripción: | Chapter Two.-- Edited by Pedro J.
