Direct linkGo´mez-Biagi, Rodolfo F.; Dicks, Andrew P. – Journal of Chemical Education, 2015
A synthetic procedure is outlined where upper-level undergraduate organic chemistry students perform a two-week, semimicroscale "aza"-Baylis-Hillman reaction to generate an allylic sulfonamide product. Students evaluate several green chemistry reaction metrics of industrial importance (process mass intensity (PMI), E factor, and reaction…

Edgar, Landon J. G.; Koroluk, Katherine J.; Golmakani, Mehrnaz; Dicks, Andrew P. – Journal of Chemical Education, 2014
A self-directed independent synthesis experiment was developed for a third-year undergraduate organic laboratory. Students were provided with the CAS numbers of starting and target compounds and devised a synthetic plan to be executed over two 4.5 h laboratory periods. They consulted the primary literature in order to develop and carry out an…

Mundle, Scott O. C.; Opinska, Liliana Guevara; Kluger, Ronald; Dicks, Andrew P. – Journal of Chemical Education, 2011
An upper-level mechanistic organic experiment is outlined where undergraduates measure kinetic rate constants for decarboxylation of pyrrole-2-carboxylic acid by the initial-rates method. UV spectroscopy is used to monitor reactant disappearance in both hydrochloric acid and deuterium chloride at different temperatures. Individual data are pooled…

Aktoudianakis, Evangelos; Chan, Elton; Edward, Amanda R.; Jarosz, Isabel; Lee, Vicki; Mui, Leo; Thatipamala, Sonya S.; Dicks, Andrew P. – Journal of Chemical Education, 2008
This article describes the rapid, green synthesis of a biaryl compound (4-phenylphenol) via a Pd(0)-catalyzed Suzuki cross-coupling reaction in water. Mild reaction conditions and operational simplicity makes this experiment especially amenable to both mid- and upper-level undergraduates. The methodology exposes students to purely aqueous…

Cheung, Lawrence L. W.; Styler, Sarah A.; Dicks, Andrew P. – Journal of Chemical Education, 2010
A short, semi-microscale synthesis of two 1,4-dihydropyridine drug analogues via a Hantzsch reaction is described, which is appropriate for a second-year undergraduate organic laboratory. Products are specifically chosen to highlight the biological relevance of this compound type while introducing the notion of a privileged structure.…

Simpson, Andre J.; Shirzadi, Azadeh; Burrow, Timothy E.; Dicks, Andrew P.; Lefebvre, Brent; Corrin, Tricia – Journal of Chemical Education, 2009
A laboratory experiment designed as part of an upper-level undergraduate analytical chemistry course is described. Students investigate two popular soft drinks (Red Bull Energy Drink and sugar-free Red Bull Energy Drink) by NMR spectroscopy. With assistance of modern NMR prediction software they identify and quantify major components in each…
