Design, synthesis and characterization of water soluble heterobimetallic complexes and their evaluation as aqueous biphasic hydroformylation catalysts
… The mononuclear complexes were reacted with a dimeric rhodium precursor [RhCl(COD)]2 to produce a series of novel ferrocenylimine-Rh(I) heterobimetallic complexes. Both themononuclear and heterobimetallic complexes were found to have good solubility in water of up to 11 mg/mL. The complexes …

Alkylated PTA platforms for mono- and polynuclear pre-catalysts for the aqueous biphasic hydroformylation of 1-octene
… synthesised. These ligands were reacted with the dimeric rhodium precursor, [RhCl(COD)]2, to produce the corresponding mono-, di- and trinuclear Rh(I)-PTA complexes. These complexes were then reacted with carbon monoxide to substitute the COD ligands with CO ligands, yielding the carbonyl …

Synthesis, Structure, and Catalytic Activity of Bimetallic Rhodium Complexes in the Hydroformylation and Allylic Oxidation of Alkenes
… known ligands were further reacted with the dimeric rhodium precursor [RhCl(COD)]2 producing a series of diphenylformamidinato-Rh(I) bimetallic complexes C1 – C4. The same ligands were also reacted with either the dirhodium trifluorotetraacetate [Rh2(TfOAc)4] or the traditional acetate …

Metal complexes with ligand-tethered organo-hydride donor groups - new prospects for efficient multi-electron reduction
… to N-heterocyclic carbene (NHC) ligands of rhodium(I) were found to oxidatively add to the proximal, low-valent rhodium center to afford both monomeric rhodium(III) and dimeric rhodium(II) complexes of a novel bidentate bis(NHC) ligand in which both a pyridylidene and imidazolylidine NHC …

Monometallic and multimetallic complexes as precatalysts in the hydroformylation of olefins
… new aryl ether salicylaldimine-based monomeric, dimeric, trimeric and hexameric triazolyl ligands have been synthesised. The N,O-chelating ligands were synthesised via Schiff base condensation reactions of salicylaldehyde with the bromopropylamine hydrobromide salt, followed by the azidation of …

X-ray crystal structures of: [Rh2(N-{2,4,6-CH3}C6H2)COCH3)4]•2NCC6H4 AND Ba1.5[Fe(C10H13N2O7)][Co(CN)6]•9H2O; two crystallographic challenges
… c =21.499(3)Å, V = 2609.4(6)Å<sup>3</sup>. Each rhodium had approximately octahedral coordination and was bound to another rhodium atom, two nitrogens (<em>trans</em> to each other), two oxygens (<em>trans</em> to each other), and one benzonitrile nitrogen (<em>trans</em> to rhodium). For …
