Synthesis of benzimidazoles in high-temperature water
The objective of this research was to conduct constructive organic chemistry in water and to achieve yields that were comparable to, or better than, those in conventional media. The synthesis of
Control of copper(I) iodide architectures by ligand design: angular versus linear bridging ligands.
A family of coordination polymers formed by the reaction of copper(I) iodide with a range of angular bidentate or tridentate N-donor ligands is reported, which exhibits a highly unusual three-dimensional structure in which the pypm ligand bridges two-dimensional brick-wall (CuI)(infinity) sheets.
Novel Metal−Organic Frameworks Derived from Group II Metal Cations and Aryldicarboxylate Anionic Ligands
Reaction of magnesium, calcium, strontium, and barium salts with a range of dicarboxylic acids [benzene-1,4-dicarboxylic acid (H2BDC), naphthalene-2,6-dicarboxylic acid (H2NDC),
Reduction and selective oxo group silylation of the uranyl dication
It is shown that placing the uranyl dication within a rigid and well-defined molecular framework while keeping the environment anaerobic allows simultaneous single-electron reduction and selective covalent bond formation at one of the two uranyl oxo groups.
Bent metal carbene geometries in amido N-heterocyclic carbene complexes.
Lithium(I) and uranium(VI) amido-tethered Bu(t)-substituted N-heterocyclic carbene (NHC) complexes exhibit very distorted metal-carbene bonds, suggesting a dominance of electrostatic character in closed-shell electropositive metal- carbene bonds.
A porous framework polymer based on a zinc(II) 4,4'-bipyridine-2,6,2',6'-tetracarboxylate: synthesis, structure, and "zeolite-like" behaviors.
The robust metal-organic framework compound, [Zn(2)(L)](infinity) (II), which has very high thermal stability and is chemically inert, is synthesized by hydrothermal reaction of ZnCl(2) and 4,4'-bipyridine-2,6,2',6'-tetracarboxylic acid.
Asymmetric lithium(I) and copper(II) alkoxy-N-heterocyclic carbene complexes; crystallographic characterisation and Lewis acid catalysis.
A one-pot synthesis of a wide range of bidentate, alkoxide-N-heterocyclic carbene ligands provides new lithium alkoxy-carbenes and a range of covalently bound organometallic Cu(II) carbene complexes,
Equatorial ligand substitution by hydroxide in uranyl Pacman complexes of a Schiff-base pyrrole macrocycle.
The synthesis of the mono-uranyl complex [UO(2)(THF)(H(2)L(Me))] of a ditopic Schiff-base pyrrole macrocycle is described and is shown to adopt a Pacman wedge-shaped structure in which the uranyl
Phenolate and phenoxyl radical complexes of Co(II) and Co(III).
These studies have demonstrated that the chemical properties of [M(II)((R)L*)(( R)L)(2)](+)(M = Co, Cu, Zn) are highly dependent on the nature of both the ligand and the metal centre.
Anion control over interpenetration and framework topology in coordination networks based on homoleptic six-connected scandium nodes.
Variation of anion, solvent and conditions critically affects the structures of products formed, and the series of polymers reported herein illustrates how tectons based upon (4,4) grids can be combined and distorted to form non-NaCl topologies and even cross-bridged, multiply interpenetrated diamondoid materials.
