Heterogeneous Catalyst Paper Published

11/20/2020

0 Comments

 
A collaborative paper between the Shaughnessy, Martin Bakker, and Yuping Bao groups at UA has been published in the Journal of Sol-Gel Science and Technology.  The paper describes the one-pot synthesis of heirarchically porous carbon containing nickel nanoparticles by incorporation of nickel-salen complexes in the carbon sol-gel synthesis.  The resulting nickel-containing materials were effective catalysts for the reduction of 4-nitrophenol.

Inorganic Chemistry Paper Published

4/9/2020

0 Comments

 
The last paper from Dr. Kerry Barnett's dissertation has been published in Inorganic Chemistry in collaboration with the Dixon Group.  This paper provides a detailed structural analysis of the palladium complexes of trineopentylphosphine ligands using computational and experimental data.  The highly flexible trineopentylphosphine ligand adopts a very sterically demanding conformation when coordinated to 1- or 2-coordinate palladium centers.  Unusually, this very sterically demanding ligand is highly pyramidalized due to the low back-side strain of the neopentyl groups.  When coordinated to a 3- or 4-coordinate palladium center, trineopentylphoshine adopts a less sterically demanding conformation.
