Hu paper on structural characterization of trineopentylphosphine complexes published.

9/25/2019

A paper by Dr. Ethan Hu entitled, "Synthesis, Structural Characterization, and Coordination Chemistry of (Trineopentylphosphine)palladium(aryl)bromide Dimer Complexes ([(Np3P)Pd(Ar)Br]2)," was published in Inorganic Chemistry. Co-authors on the paper are, Monica Vasiliu, Deidra Gerlach, Fengrui Qu, Trent Stein, Dr. David Dixon, and Kevin Shaughnessy. The paper describes the structure of the trineopentylphosphine ligand in [(Np3P)Pd(Ar)Br]2 complexes as a function of the steric demand of the aryl group. The trineopentylphosphine is highly flexible allowing it to accommodate other sterically demanding ligands.

A paper authored by Kerry Barnett, James Howard, Renee Stullich, Adam Shipley, and Colin Treager entitled, "Air-Stable [(R3P)PdCl2]2 Complexes of Neopentylphosphines as Cross- Coupling Precatalysts: Catalytic Application and Mechanism of Catalyst Activation and Deactivation," was published in Organometallics. This paper describes the use of [(R3P)PdCl2]2 complexes as catalysts in the Suzuki coupling. A study of the mechanism of conversion of the Pd(II) precatalyst to the Pd(0) active species showed that palladacycle formation was a competitive pathway in acetonitrile. Switching the solvent to toluene eliminated formation of the palladacycle byproduct. This solvent switch allowed a 50-fold decrease in catalyst loading.

A collaborative paper involving the Shaughnessy and Martin Bakker groups in Chemistry and the John van Zee group in Chemical & Biological Engineering was published in the Journal of Sol-Gel Science and Technology. The paper entitled, "Copolymerization of Transition Metal Salen Complexes and Conversion into Metal Nanoparticles Supported on Hierarchically Porous Carbon Monoliths: A One Pot Synthesis," describes the incorporation of metal salen complexes in a carbon sol-gel. Pyrolysis provides a carbon material with metal nanoparticles.
