Stabilization of a two-coordinate, acyclic diaminosilylene (ADASi): completion of the series of isolable diaminotetrylenes, :E(NR(2))(2) (E = group 14 element).
An extremely bulky boryl-amide ligand has been utilised in the preparation of the first isolable, two-coordinate acyclic diaminosilylene (ADASi), shown to have a frontier orbital energy separation, and presumed level of reactivity, intermediate between those of the two classes of previously reported isolable two- coordinate, acYclic silylenes.

Cooperative bond activation and catalytic reduction of carbon dioxide at a group 13 metal center.
The hydride complex derived from the activation of H2 is shown to be a competent catalyst for the highly selective reduction of CO2 to a methanol derivative and represents the first example of a reduction process of this type catalyzed by a molecular gallium complex. Expand
Utilisation of a lithium boryl as a reducing agent in low oxidation state group 15 chemistry: synthesis and characterisation of an amido-distibene and a boryl-dibismuthene.
The first examples of an amido-distibene, L(†)Sb[double bond, length as m-dash]SbSbL(†), and a boryl dibismuthene, which have been prepared by reaction of a lithium boryL complex, (THF)2LiB(DAB), with extremely bulkyAmido-group 15 dihalide precursor compounds. Expand
Coordination and activation of Al-H and Ga-H bonds.
The modes of interaction of donor-stabilized Group 13 hydrides (E=Al, Ga) were investigated towards 14- and 16-electron transition-metal fragments and β-Diketiminato ('nacnac')-st stabilized systems, {HC(MeCNDipp)2 }EH2, show more diverse reactivity towards Group’6 carbonyl reagents. Expand
Formation of sub-valent carbenoid ligands by metal-mediated dehydrogenation chemistry: coordination and activation of H2Ga{(NDippCMe)2CH}
Reactions of the β-diketiminato (‘Nacnac’) stabilized gallium dihydride H2Ga{(NDippCMe)2CH} with a range of mono- and dinuclear metal carbonyl reagents are characterized by loss of dihydrogen andExpand
Electronic Delocalization in Two and Three Dimensions: Differential Aggregation in Indium "Metalloid" Clusters.
Indium boryl precursors to give two- and three-dimensional M-M bonded networks is influenced by the choice of supporting ligand, which gives a near-planar (and weakly aromatic) tetranuclear [In4 (boryl)4 ]2- system. Expand
Structural snapshots of concerted double E-H bond activation at a transition metal centre.
Bond activation at a transition metal centre is a key fundamental step in numerous chemical transformations. The oxidative addition of element-hydrogen bonds, for example, represents a critical stepExpand
Al-H σ-bond coordination: expanded ring carbene adducts of AlH3 as neutral bi- and tri-functional donor ligands.
Thermally robust expanded ring carbene adducts of AlH3 have been synthesized with a view to probing their ligating abilities via Al-H σ-bond coordination, but interaction with [Mo(CO)3] results in μ:κ(1),κ( 1) and μ:τ(2),τ(1) bridging linkages rather than terminal κ(3) binding. Expand
Characterisation of the paramagnetic [2Fe-2S]+ centre in palustrisredoxin-B (PuxB) from Rhodopseudomonas palustris CGA009: g-matrix determination and spin coupling analysis.
The accurate description of the g-matrix orientation and magnetic moment of this [2Fe-2S](+) cluster enable it to be utilised as a paramagnetic spin probe, for example, to measure electron-electron distances. Expand
Chapter One - Coordination and Activation of EH Bonds (E = B, Al, Ga) at Transition Metal Centers
Developments in the coordination chemistry of BH, AlH, and GaH bonds at transition metal centers are reviewed, with particular emphasis on factors influencing electronic/geometric structure and bondExpand
