Mark A. Chrisman; Michael J. Goldcamp; Alexis N. Rhodes; Jared Riffle – Journal of Chemical Education, 2023
This report describes a laboratory experiment for an undergraduate-level inorganic chemistry or biochemistry course involving the study of the kinetics of the catecholase activity of a synthetic nickel­(II)-oximate complex. A model substrate, 3,5-di-tert-butylcatechol(DBC), undergoes aerobic oxidation to 3,5-di-tert-butylbenzoquinone (DBQ) in the…

Rapp, Teresa L.; Phillips, Susan R.; Dmochowski, Ivan J. – Journal of Chemical Education, 2016
The study of ruthenium polypyridyl complexes can be widely applied across disciplines in the undergraduate curriculum. Ruthenium photochemistry has advanced many fields including dye-sensitized solar cells, photoredox catalysis, lightdriven water oxidation, and biological electron transfer. Equally promising are ruthenium polypyridyl complexes…

Sues, Peter E.; Cai, Kuihua; McIntosh, Douglas F.; Morris, Robert H. – Journal of Chemical Education, 2015
Asymmetric transfer hydrogenation is an important transformation for the production of fine chemicals. Traditionally, platinum group metals are used to catalyze this reaction, but recent pressure for greener practices has driven the development of base-metal catalysts. Due to the growing interest in this area of research, the underlying concepts…

Synthesis and Base Hydrolysis of a Cobalt(III) Complex Coordinated by a Thioether Ligand
Peer reviewed Peer reviewed
Direct linkDirect link
Roecker, Lee – Journal of Chemical Education, 2008
A two-week laboratory experiment for students in advanced inorganic chemistry is described. Students prepare and characterize a cobalt(III) complex coordinated by a thioether ligand during the first week of the experiment and then study the kinetics of Co-S bond cleavage in basic solution during the second week. The synthetic portion of the…
