Monodentate phosphine-ligated nickel compounds, e.g., [Ni(PPh3)4] are relevant as active catalysts across a broad range of reactions. This report expands upon the coordination chemistry this family, offering reactivity allyl- and vinyl-substituted diphenylphosphine (PPh2R) with [Ni(COD)2] (COD = 1,5-cyclooctadiene). These reactions provide three-coordinate dinickelacycles that intermolecularly ...

Transition-metal complexes of cyclopropenes occur as fleeting intermediates numerous metal-catalyzed organic transformations. A heavier analogue has now been obtained from the reaction an NHC-stabilized silagermenylidene, bis(1,5-cyclooctadiene)nickel(0), and 1 equiv N-heterocyclic carbene (NHC). The residual chloro functionality at germanium end coordinated Ge?Si moiety thus formed 1H-disilage...

The valorisation of biomass-derived platform chemicals via catalytic hydrogenation is an eco-friendly tool which allows us to recover bio-based building blocks and produce fine with high industrial appeal. In the present study, a novel surfactant-type triazolyl-thioether ligand was prepared, showing excellent activity in presence bis(1,5-cyclooctadiene)diiridium(I) dichloride [Ir(COD)Cl]2 for f...

Thioether-phosphite ligands (SP’s) with axially chiral (S)-H0- or (S)-H8-binaphthyl moiety and their [Rh(COD)(SP)]BF4 complexes have been synthesized to study coordination chemistry catalytic features compare them those of the structurally analogous phosphine-phosphites (PP’s). NMR exchange studies on showed selective 1,5-cyclooctadiene dynamics. Firm evidence has found that this fluxional proc...

The decomposition of the organometallic ruthenium precursor [Ru(COD)(COT)] (COD: 1,5-cyclooctadiene; COT: 1,3,5cyclooctatriene) in mild conditions (20 C, 3 bar H2) in n-pentane leads, in the presence of octylsilane (H3 SiC8H17) to the formation of stable Ru nanoparticles with narrow size distribution. The solids obtained after washing and drying were fully characterized by elemental analysis, T...

The synthesis of new functionalised 6- and 7-membered NHC (N-heterocyclic carbene) precursors bearing anisidyl or pyridine N-substituents, both symmetrically and non-symmetrically substituted is reported. Their corresponding rhodium(i) and iridium(i) complexes, M(COD)(NHC)Cl, were also prepared and characterised. The unusual Rh(iii)/Rh(i) salt, [Rh(eta(2)-NHC-py)(2)Cl(2)][Rh(COD)Cl(2)], was obt...
