Resonance energies are shown to be quasithermodynamic in character. Hence, they are generally unsuitable as bases for anticipating kinetic stabilities. Examples are provided, leading to the conclusion ...

The X-ray structure of berkelocene shows a Bk(IV) ion sandwiched between two substituted cyclooctatetraene ligands. (Stefan Minasian/Berkeley Lab) The configuration of this molecule, 'berkelocene', is ...

Scientists have achieved the first real-time visualization of how 'excited-state aromaticity' emerges within just hundreds of femtoseconds and then triggers a molecule to change from bent to ...

The synthetic element berkelium has been trapped between two carbon rings to create berkelocene for the first time, one of the heaviest organometallic structures ever created. Berkelium, element 97, ...

Self-healing fluorophores guide the way Chemicals called triplet state quenchers, such as cyclooctatetraene, counteract this phenomenon but also tend to gum up the works. "Cyclooctatetraene is ...

Each cyclooctatetraene carried two bulky triisopropylsilyl groups that forced the metallocenes to bend as they stacked (Nature 2023, DOI: 10.1038/s41586-023-06192-4). “The discovery of the ...

Rapid and accurate mRNA translation requires efficient codon-dependent delivery of the correct aminoacyl-tRNA (aa-tRNA) to the ribosomal A site. In mammals, this fidelity-determining reaction is ...

The method uses a cobalt-catalyzed reaction to combine cyclooctatetraene (C 8 H 8) with an alkyne bearing one or two pinacol boronate esters (Bpin). A rearrangement driven by ultraviolet light ...

Cyclooctatetraene (COT) is a poster child for nonaromatic molecules. An isomer of tub-shaped COT, with one of the ring double bonds changed from the usual cis form to a trans one, lies some 23 ...
