Electrochemical removal of toxic metals from reaction media following catalysis

Following Ni-catalysed Suzuki-Miyaura cross coupling reactions, Ni is electrochemically removed on to the cathode, offering potential for recovery and reuse. The electrochemical recovery method, in combination with an analytical method developed for accurate quantification by HPLC, is expected to be broadly applicable to metal recovery following catalysis

Tethered N-heterocyclic carbene–carboranes: unique ligands that exhibit unprecedented and versatile coordination modes at rhodium

Four brand new hybrid ligands combining an N-heterocyclic carbene tethered with two isomeric nido-dicarbaundecaborane dianions, a neutral closo-dicarbadodecaborane or a closo-dicarbadodecaborane anion are described. Versatile coordination of the ligands to RhI is demonstrated, in which both NHC and carborane moieties covalently coordinate a metal centre

A small tris(imidazolium) cage forms an N-heterocyclic carbene complex with silver(i)

A small, sterically rigid tris(imidazolium) cyclophane reacts with Ag 2O to give an Ag(i) carbene complex in which one of the imidazolium moieties remains protonated. © The Royal Society of Chemistry.Articl

A catenated imidazole-based coordination polymer exhibiting significant CO2 sorption at low pressure

A robust, porous, catenated coordination polymer based on a neutral, flexible imidazole-derived tripodal ligand (a 'tripodal imidazole framework', TIF) reversibly absorbs vapours and gases, particularly CO2. © The Royal Society of Chemistry 2009.Articl

A new reaction pathway in organophosphorus chemistry: competing SN2- and AE'-pathways for nucleophilic attack at a phosphorus-cage compound

Competition: A combination of 31P NMR spectroscopic and calculational studies have shown that nucleophilic substitution in the phosphorus-carbon cage compound ClP3(CtBu)2 occurs through competing SN2- and AE-type reaction pathways (see scheme for model compound ClP3(CH)2). The AE mechanism results in the formation of a C2v-symmetric intermediate prior to release of the chloride ion
