Continuous flow homogeneous catalysis using ionic liquid/supercritical fluid biphasic systems [PDF]
, 2010 Ionic liquid/scCO₂ biphasic systems have been studied as a possible solution to the main problems concerning homogeneous catalysis reactions such as, the product/catalyst separation, the catalyst retention in the reaction medium and the use of organic

Silicon-oriented regio- and enantioselective rhodium-catalyzed hydroformylation
Nature Communications, 2018 Hydroformylation of 1,2-disubstituted alkenes usually occurs at the α position of the directing heteroatom. Here, the authors report the asymmetric rhodium-catalyzed hydroformylation of 1,2-disubstituted alkenylsilanes with excellent regioselectivity at ...

Hydroformylation of Unsaturated Dicarboxylic Esters with Rhodium Containing Catalysts
CHIMIA, 1986 The regioselectivity observed in carbonyl-rhodium catalyzed hydroformylation of dimethyl itaconate (1a), which leads to the preferential formation of dimethyl 2-(formylmethyl)-butandioate (3a) is completely reversed by the modification of the catalyst ...

Ir Complexes With Mixed‐Valent Bidentate Ligands: From Complex Synthesis to Catalytic Application
Chemistry – A European Journal, EarlyView.ABSTRACT The bidentate ligands Ph2P(E)NHPPh2 (E = S, Se) feature phosphorous atoms in two different oxidation states and provide the potential to tune chemical reactivity through the choice of donor E. The mononuclear complexes [Ir(COD){κ2‐P,E‐Ph2P(E)NPPh2}] (E = S 1a, Se 1b) were prepared from the dimer [IrClCOD]2 (COD = 1,5‐cyclooctadiene) and the ...

EcoEnergy, EarlyView.Mixed‐ligand Ag–triazole MOF precursors reconstruct into ligand‐shelled Ag nanoparticle electrocatalysts that retain detectable O/S‐derived interfacial species. By combining ligand‐ratio and potential control, the CO2‐to‐syngas output can be tuned across H2‐rich, near‐equimolar, and CO‐rich regimes.
