Developing Critical Thinking Skills: The "Sabotaged" Synthesis of Methyl p-Bromobenzoate  Eric J. Mahan and Mary Alice Nading
Before beginning an experiment, students are told that someone might have sabotaged their experiment to produce other-than-expected results. The objective is to perform the experiment, determine if any sabotage has occurred, and, if so, identify the changes that were made to the reagents as well as the person responsible.

The Conversion of Carboxylic Acids to Ketones: A Repeated Discovery  John W. Nicholson and Alan Wilson
This article describes the history of the reaction converting carboxylic acids to ketones. The reaction has been rediscovered several times, yet has actually been known for centuries.

Organic Acids without a Carboxylic Acid Functional Group  G. V. Perez and Alice L. Perez
This paper presents several organic molecules that have been labeled as acids but do not contain a carboxylic acid functional group. Various chemical principles such as pKa, tautomerization, aromaticity, conformation, resonance, and induction are explored.

A One-Step Synthesis of Cinnamic Acids Using Malonic Acid: The Verley-Doebner Modification of the Knoevenagel Condensation  Kolb, Kenneth E.; Field, Kurt W.; Schatz, Paul F.
With this procedure malonic acid itself, rather than its diester, can be effectively condensed with benzaldehyde to produce trans-cinnamic acid.
