Xanthene‐Based FLPs Featuring Perchloroarylborane Substitutents: Interplay of Noncovalent Aggregation and Dihydrogen Activation

Aisling Roper, Agamemnon E. Crumpton, Dermot O’Hare, Simon Aldridge

ABSTRACT The syntheses of frustrated Lewis pairs (FLPs) based on a 4,5‐difunctionalised xanthene backbone, and featuring the pentachlorophenyl‐containing boryl groups, are reported. At a general level, this allows for systematic comparison of these systems in H 2 activation as a function of …

Heavier alkaline earth and heterobimetallic s-block “ate” complexes of a di(amido)siloxane ligand: solid-state structure and dynamic solution-phase behaviour

Matthew D. Haynes, Andrea O’Reilly, Alan F. Poole, Aisling Roper et autres

-N,O,N'-tridentate motif in 9-11. Finally, the solution-phase behaviour of 8-11 in both toluene and thf were investigated indicating the reversible dissociation of KN'' from 9-11 and the thermodynamic parameters of this process were elucidated.

Synthesis, Isolation, and Reactivity Studies of ‘Naked’ Acyclic Gallyl and Indyl Anions

Debotra Sarkar, Petra Vasko, Tihomir Gluharev, Liam P. Griffin et autres

Abstract By exploiting the electronic capabilities of the N‐heterocyclic boryloxy (NHBO) ligand, we have synthesized “naked” acyclic gallyl [Ga{OB(NDippCH) 2 } 2 ] − and indyl [In{OB(NDippCH) 2 } 2 ] − anions (as their [K(2.2.2‐crypt)] + salts) through K + abstraction …

A nucleophilic beryllyl complex via metathesis at [Be–Be]2+

Josef T. Boronski, Agamemnon E. Crumpton, Aisling Roper, Simon Aldridge

Abstract Owing to its high toxicity, the chemistry of element number four, beryllium, is poorly understood. However, as the lightest elements provide the basis for fundamental models of chemical bonding, there is a need for greater insight into the properties of beryllium. …

Reversible [4 + 1] Cycloaddition of Arenes by a “Naked” Acyclic Aluminyl Compound

Debotra Sarkar, Petra Vasko, Aisling Roper, Agamemnon E. Crumpton et autres

High Resolution Image Download MS PowerPoint Slide The large steric profile of the N-heterocyclic boryloxy ligand, –OB(NDippCH) 2, and its ability to stabilize the metal-centered HOMO, are exploited in the synthesis of the first example of a “naked” acyclic aluminyl complex, [K(2.2.2-crypt)][Al{OB(NDippCH) …

Bis(Aluminyl)Magnesium: A Source of Nucleophilic or Radical Aluminium‐Centred Reactivity

Liam P. Griffin, Mathias A. Ellwanger, Jonathon Clark, William K. Myers et autres

Abstract The homoleptic magnesium bis(aluminyl) compound Mg[Al(NON)] 2 (NON=4,5‐bis(2,6‐diisopropylanilido)‐2,7‐di‐tert‐butyl‐9,9‐dimethylxanthene) can be accessed from K 2 [Al(NON)] 2 and MgI 2 and shown to possess a non‐linear geometry (∠Al−Mg−Al=164.8(1)°) primarily due to the influence of dispersion interactions. This compound acts a four‐electron reservoir …
