Fonseca, Custódia S. C. – Journal of Chemical Education, 2017
Sigmatropic rearrangement is one of the main classes of pericyclic reactions, which does not necessarily mean that these rearrangements have a pericyclic mechanism. The allylic saccharin derivative O-cinnamylsaccharin can isomerize into N-cinnamylsaccharin in the polar solvent system toluene/triethylamine in a reaction time of 2 h at 110°C. The…

Hare, Stephanie R.; Tantillo, Dean J. – Journal of Chemical Education, 2017
When new concepts, models, or theories are introduced in a course, their presentation should be accurate, even if depth is not the goal. In a recent publication in this Journal, the Woodward-Hoffmann rules were invoked in the context of a new laboratory experiment, but the associated description was inaccurate. Here we aim to clarify the…

Hendel, Samuel J.; Young, Elizabeth R. – Journal of Chemical Education, 2016
Electrochemical analysis is an important skill to teach in chemistry curricula because it is a critical tool in current high-impact chemical research. Electrochemistry enables researchers to analyze a variety of systems extending from molecules to materials that encompass research themes ranging from clean energy to substrate activation in…

Weiser, Beverly L.; Reed, Deborah K.; Kethley, Caroline I.; Mathes, Patricia G. – Learning Disability Quarterly, 2012
In October 2011, Council for Learning Disabilities' (CLD's) research committee members (i.e., authors of this article) presented their "Must Reads" at the organization's 33rd Annual International Conference on Learning Disabilities. In this article, the presenters summarize a few of their selected articles and state why each article is a "Must…
