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.

    Controlled doping of organic semiconductors is required to enhance charge injection in organic electronics, but the lack of suitable n-dopants with small ionization energy remains elusive. Here, the authors report air-stable metals that act as strong n-dopants in molecules with chelating ligands.

    Low-molecular-weight, highly branched polyethylenes are attractive candidates for synthetic lubricants, but their efficient production is constrained by a lack of effective catalytic methods. While conventional group IV transition metal catalysts produce diverse polyethylenes on a huge scale, they are unable to produce highly branched polyethylenes. Here a hydrocarbon-soluble organozirconium precatalyst and borate cocatalyst produce the desired polyethylenes with excellent activity and branch selectivity.

    Finding new thermoelectric materials that can achieve high performance is vital to realizing the potential of future energy harvesting technology. Here, through computation methods, the authors identify two high-performance full-Heusler thermoelectric compounds with high intrinsic band degeneracy.

    Carbonyl complexes have been studied extensively thanks to their rich substitution and redox chemistry, but most homoleptic transition metal carbonyl complexes isolated in the condensed phase are neutral or anionic. Here, the authors isolate two homoleptic carbonyl radical cations in the condensed phase; both 17-electron [Cr(CO)6]•+ salts.

    In actinide chemistry, a longstanding bonding model describes metal-ligand binding using 6d-orbitals, with the 5f-orbitals remaining non-bonding. Here the authors explore the inverse-trans-influence — a case where the model breaks down — finding that the f-orbitals play a crucial role in dictating a trans-ligand-directed geometry.

    Dilanthanide complexes that possess radical bridges exhibit enhanced magnetic exchange coupling, affording molecular magnets with high blocking temperatures. Here, the authors explore a series of dilanthanide-encapsulated fullerenes where the radical bridge is taken to its limit and the role is played by a single unpaired electron.

    Certain frustrated Lewis pairs can undergo single electron transfer to give frustrated radical pairs. Such radical pairs have been implicated as important species in the activation of small molecules such as dihydrogen.

    Artificial metalloenzymes generally consist of a synthetic (organo)metallic catalyst incorporated into a protein. Asymmetric catalysis by such metalloenzymes could result by virtue of the chiral protein environment. Now, redox-sensitive anchoring enables reversible incorporation of an iridium catalyst for transfer hydrogenation.

    Iridium chelates are attractive catalysts for asymmetric transfer hydrogenation. The mode through which a chelating ligand binds iridium turns out to have a striking effect on catalytic activity and enantioselectivity.
