Fabrication of Dendritic Gold Nanoparticles by Use of an Ionic Polymer Template

Paul Joseph Dyson, Zhaofu Fei, Dongbin Zhao

A facile method for the fabrication of dendritic gold nanoparticles (NPs) by use of an ionic polymer template has been developed. In situ generation of an imidazolium-based (cationic) polymer, poly[1-methyl-3-(4-vinylbenzyl)imidazolium], with AuCl4- counte ...

Neutral ligands with exceptional donor ability for palladium-catalyzed alkene hydrogenation

With four site: Catalytic olefin hydrogenation is observed with palladium complexes when the N-heterocyclic carbene ligand is changed from the normal C2- to the unusual C4-bonding mode (see scheme). In a cis coordinating framework, the electron density at ...

Catalytic Activity of Bis-phosphine Ruthenium(II)-Arene Compounds: Chemoselective Hydrogenation and Mechanistic Insights

Paul Joseph Dyson

Bis-phosphine Ru(II)-arene complexes are highly active and chemoselective catalysts for the hydrogenation of aldehydes in the presence of olefinic bonds. Mechanistic studies, including comparisons with a structural analog, reactions of an isolated hydride ...
