Polymer-Supported Reagents and 1H–19F NMR Couplings: The Synthesis of 2-Fluoroacetophenone  Nicola Pohl and Kimberly Schwarz
Describes an experiment in which 2-bromoacetophenone is converted to 2-fluoroacetophenone using a solid-phase nucleophilic fluorine source. The experiment introduces students to the utility of solid-phase reagents in organic synthesis, to NMR-active nuclei other than 1H without the requirement of a special NMR probe, and to the unique uses of fluorine in molecular design.

A Discovery-Based Experiment Involving Rearrangement in the Conversion of Alcohols to Alkyl Halides  Richard A. Kjonaas and Ryand J. F. Tucker
This article reports a discovery-based experiment in which students convert three alcohols to alkyl halides under acidic conditions and record the 13C NMR spectrum in each case. By comparing the number of resonances observed with the number of resonances predicted for each possible product, students draw several conclusions about the resulting rearrangement.

Synthesis of Unsymmetrical Alkynes via the Alkylation of Sodium Acetylides. An Introduction to Synthetic Design for Organic Chemistry Students  Jennifer N. Shepherd and Jason R. Stenzel
Teams of students design a microscale synthesis of an unsymmetrical alkyne using commercially available terminal alkynes and alkyl halides and characterize the resulting products using TLC, IR, and 1H NMR spectroscopy. Depending on the chosen reactants, students observe both substitution and elimination products, or in some cases, no reaction at all.

Mechanism Templates: Lecture Aids for Effective Presentation of Mechanism in Introductory Organic Chemistry  Brian J. McNelis
To promote active student learning of mechanism in introductory organic chemistry, hand-outs have been developed with incomplete structures for reaction processes depicted, which are called mechanism templates. The key to these lecture aids is to provide only enough detail in the diagram to facilitate notetaking, ensuring that these templates are dynamic learning tools that must be utilized by an engaged and alert student.
