Journal ArticleDOI
Reduction vs. Addition: The Reaction of an Aluminyl Anion with 1,3,5,7-Cyclooctatetraene.
TL;DR: DFT calculations indicate significant aromatic character, consistent with reduction to [COT]2- .
Journal ArticleDOI
Isolation and Characterization of a Bismuth(II) Radical
Ryan J. Schwamm,Jeffrey Harmer,Matthias Lein,Christopher M. Fitchett,Simon Granville,Martyn P. Coles +5 more
TL;DR: X-ray crystallographic measurements are consistent with a two-coordinate bismuth in the +2 oxidation state with no short intermolecular contacts, and solid-state SQUID magnetic measurements indicate a paramagnetic compound with a single unpaired electron.
Journal ArticleDOI
A Stable Calcium Alumanyl.
Ryan J. Schwamm,Martyn P. Coles,Michael S. Hill,Mary F. Mahon,Claire L. McMullin,Nasir A. Rajabi,Andrew S. S. Wilson +6 more
TL;DR: A seven‐membered N,N′‐heterocyclic potassium alumanyl nucleophile is introduced and utilised in the metathetical synthesis of Mg−Al and Ca−Al bonded derivatives, allowing a rationalisation of the greater reactivity of the heavier group 2 species implied by an initial assay of their reactivity.
Journal ArticleDOI
Bi-P Bond Homolysis as a Route to Reduced Bismuth Compounds and Reversible Activation of P4.
TL;DR: Bismuth diphenylphosphanides Bi(NONR )(PPh2 ) (NonR =[O(SiMe2 NR)2 ], R=tBu, 2,6-iPr2 C6 H3 , Aryl) undergo facile decomposition via single-electron processes to form reduced Bi and P species.
Journal ArticleDOI
Catalytic oxidative coupling promoted by bismuth TEMPOxide complexes
TL;DR: These compounds are active catalysts for oxidative coupling of TEMPO and silane substrates, believed to proceed via metathesis of Bi-O and Si-H bonds followed by decomposition of bismuth-hydride intermediate species.
