Organometallic chemistry

Organometallic chemistry is the study of the synthesis, structure and reactivity of chemical compounds that contain metal-carbon bonds. These compounds are often used as homogeneous catalysts.

    Carbyne anions are under explored and poorly understood, owing to their isolation being unknown. Now, the synthesis and isolation of copper phosphinocarbyne anion complexes are reported. Displaying the reactivity of a carbyne anion, these complexes provide access to singlet carbenes, alkenes and ethenimines.

    Stereodefined 1,2-dimetallated alkenes are underexplored in organic synthesis due to their relatively low stability. Now, the reductive anti-1,2-dimetallation of alkynes provides access to trans-1,2-dimagnesio- and 1,2-dialuminoalkenes. The process uses sodium dispersion as a reducing agent with organomagnesium and organoaluminium halides as reduction-resistant electrophiles.

    Aromaticity is a ubiquitous concept in organic chemistry yet it is less widespread for inorganic species. Now the cluster [(CpRu)3Bi6], obtained as part of a soluble salt, has been shown to exhibit aromatic behaviour referred to as φ-type, owing to a highly regular {Bi6} substructure causing a non-localizable molecular orbital of \(f_{z^3}\)-like symmetry.

    Reactions induced by σ-aromaticity are uncommon compared with those induced by π-aromaticity. Now, a π- and σ-aromaticity relay strategy is developed to realize the ring contraction of metallacyclobutadiene to metallacyclopropene. This reaction involves the release of π-antiaromaticity to afford a π-aromatic intermediate, followed by ring reclosure to form σ-aromatic metallacyclopropene.

    Converting low-cost inorganic chemicals into value-added organic chemicals is a longstanding goal in chemistry. Here the authors describe a silver-catalysed chemoselective carbene N−H insertion reaction, providing access to primary amines from aqueous ammonia and diazo compounds.

    Reductive anti-1,2-dimetallation of alkynes proceeds through the use of sodium dispersion as a reducing agent and an organomagnesium or organoaluminum halide as a reduction-resistant electrophile. The reaction stereoselectively generates trans-1,2-dimagnesio- or 1,2-dialuminoalkenes, which show useful reactivity.

    The study of rare isotopes, including many in the f-block, is a key step to advancing our fundamental understanding of these elements, but their scarcity poses challenges. Now, minute amounts of such materials have been isolated and characterized through complexation with polyoxometalate clusters.

    An article in the Journal of the American Chemical Society reports azobenzene crystals that roll continuously under visible light, thanks to crystal packing effects that shift azobenzene’s light-responsive window.

    β-Hydride and β-heteroatom eliminations are competitive processes in many Pd-catalysed reactions but general strategies for controlling this selectivity have not been established. Now, a mechanistic study of Pd-alkyl complexes demonstrates that the choice of phosphine ligands and leaving groups controls selectivity.

    Remarkably simple conditions can convert fac-Ir(iii) arylpyridine complexes to the less thermodynamically stable mer-isomers. The organoiridium complexes are considered highly effective luminescent molecular switches.
