The Comparative Nucleophilicity of Naphthoxide Derivatives in Reactions with a Fast-Red TR Dye  Cheryl M. Mascarenhas
In this experiment, organic chemistry students perform reactions between three naphthyl acetate derivatives and the diazonium salt Fast-Red TR. Students discover under what conditions the hydrolysis and electrophilic aromatic substitution is fastest and slowest, allowing them to conclude that latter, rather than the former, is rate-limiting.

Generation, Isolation, and Characterization of a Stable Enol from Grignard Addition to a Bis-Ester. A Microscale Experiment for the Undergraduate Organic Chemistry Laboratory  Olivier J.-C. Nicaise, Kyle F. Ostrom, and Brent J. Dalke
A microscale experiment for the undergraduate organic chemistry laboratory that consists of preparing and characterizing an alpha-ketoester and its corresponding, remarkably stable enol form, has been developed. The reaction is that of a Grignard reagent with a bis-ester. A difference in reaction temperature is responsible for the selective generation of the alpha-ketoester and the enol ester. Analysis of spectral data (1H NMR and IR) and a knowledge of organic reactions allows the students to determine the detailed structure of the two reaction products and also to suggest a mechanism for their formation. This experiment introduces students to the concept of stability of the tetrahedral intermediate in acyl-transfer reactions. It also gives them a taste of the unexpected.

Sharpless Asymmetric Dihydroxylation: Effect of Alkene Structure on Rates and Selectivity  Alan C. Spivey, R. Hanson, N. Scorah, and S. J. Thorpe
Each student is assigned an alkene and performs three dihydroxylation reactions: one racemic and two enantioselective variants. The products are characterized by 1H NMR, IR, MS, [a]D20, and chiral chromatography (HPLC or GC). Comparison by the students of their results with those reported in the literature, particularly the extensive work of Sharpless, allows an exploration of the validity of Sharpless's mnemonic for predicting the stereochemical outcome of these reactions.
