Gehman, Courtney A.; Hantz, Eric R.; Hamann, Christian S. – Journal of Chemical Education, 2021
[superscript 1]H NMR spectroscopy is a molecular characterization technique that is ubiquitously used in research and teaching laboratories alike. Strategic deuteration of molecules is a commonly employed technique in the deconvolution of [superscript 1]H NMR signals. Here this approach is applied in a second-year chemistry course in which…

Savakinas, Mallory V.; Frey, Olivia M.; Piro, Nicholas A.; Rhile, Ian J.; Hamann, Christian S. – Journal of Chemical Education, 2021
Friedel-Crafts alkylation reactions using a curated set of alcohols provide students with the opportunity to combine the study of electrophilic aromatic substitution with carbocation rearrangements. In this experiment students may be presented with up to nine alcohols that yield six products, all synthesized under identical reaction conditions.…

Polito, Victoria; Hamann, Christian S.; Rhile, Ian J. – Journal of Chemical Education, 2010
In this discovery laboratory, students performed electrophilic aromatic substitution reactions between 1,4-dimethoxybenzene and either 2-methyl-2-butanol or 3-methyl-2-butanol with sulfuric acid as a catalyst. The carbocation from 3-methyl-2-butanol undergoes a hydride shift, and hence, both reactions afford…

Reed, Nicole A.; Rapp, Robert D.; Hamann, Christian S.; Artz, Pamela G. – Journal of Chemical Education, 2005
Dess-Martin periodinane oxidation is an experiment that provides an avenue to the introduction of Circular Dichroism (CD) spectroscopy in organic chemistry curriculum as a diagnostic tool for examination of the results of a familiar reaction, and absolute configuration. From the experiment, students increased their understanding of CD theory and…
