NOVEL RHODIUM CLUSTER-CATALYZED REDUCTION OF NITROPROPANE TO PROPIONITRILE UNDER CO AND H2O

Kinetic Study, Modeling and Simulation of Homogeneous Rhodium-Catalyzed Methanol arbonylation to Acetic Acid

Thermodynamic restrictions and simultaneous effects of operational conditions on the homogeneous rhodium-catalyzed carbonylation of methanol are studied in this line of research. It is shown that the general NRTL-Virial model can be appropriated to study thermodynamics of the carbonylation. It is obtained that the reaction is kinetically and thermodynamically reasonable at temperatures abov...

Novel monodentate spiro phosphorus ligands for rhodium-catalyzed hydrogenation reactions.

Novel monodentate phosphorus ligands containing the 1,1'-spirobiindane backbone have been synthesized and applied in the asymmetric rhodium-catalyzed hydrogenation of functionalized olefins, providing excellent enantioselectivities (up to 99.3% ee).

Regioselective Rhodium-Catalyzed Allylic Amination

Vibrational spectroscopy of CO in gas-phase rhodium cluster-CO complexes.

Infrared spectra of isolated unsaturated rhodium cluster-CO complexes in the region of the CO stretching vibration, nu(CO), are measured using a molecular beam depletion technique. These spectra provide benchmarks for interpreting values of nu(CO) that are found when CO is used to probe Rh surfaces and supported Rh nanoparticles. Supported nanoparticles have shifts of nu(CO) of as much as +100 ...

Rhodium(I)-catalyzed hydroaminomethylation of 2-isopropenylanilines as a novel route to 1,2,3,4-tetrahydroquinolines.

A new atom economical approach for the preparation of 1,2,3,4-tetrahydroquinolines can be achieved by means of the intramolecular hydroaminomethylation of 2-isopropenylanilines, mediated by an ionic diamino rhodium catalyst that does not require phosphine--this reaction is highly chemo- and regioselective, and it occurs in good isolated yields.
