Synthesis of Quaternary Ammonium Salts of Tricyclic Cationic Drugs: A One-Pot Synthesis for the Bioorganic Chemistry Laboratory  Linda S. Brunauer, Abid C. Mogannam, Won B. Hwee, and James Y. Chen
Describes a one-pot conversion of tricyclic cationic drugs to their quaternary ammonium forms for a widely used bioactive drug, chlorpromazine, a phenothiazine-based antipsychotic. The conversion of parent drug to the methylated form was evaluated by qualitatively measuring its ability to induce alterations in the shape of mammalian erythrocytes.

Colorful Chemical Demonstrations on the Extraction of Anionic Species from Water into Ether Mediated by Tricaprylylmethylammonium Chloride (Aliquat 336), a Liquid–Liquid Phase-Transfer Agent  Anil Joseph Pezhathinal, Kerensa Rocke, Louis Susanto, Derek Handke, Roch Chan-Yu-King, and Patrick Gordon
Provides a list of safe and easy experiments to demonstrate the extraction of colorful, water-soluble reagents by Aliquat 336 into ether. The demonstrations simulate the preliminary extractive step of an ionic species in liquidliquid phase transfer-catalyzed reactions and introduce various undergraduate chemistry concepts and principles to students.

An Organoleptic Laboratory Experiment  John M. Risley
Compounds in ten different classes of organic molecules that are used in the fragrance and food industry are provided to students. Students whiff the vapors of each compound and describe the organoleptic properties using a set of terms utilized in the fragrance and food industry. A set of questions guides students to an understanding of the relationship between structure of molecules and smell.

A separation and identification experiment for elementary organic chemistry laboratory  Laughton, Paul M.
The student selects a test tube containing two unknowns and is told only that they have been selected from two of three possible groups: a primary or tertiary amine, an aldehyde or ketone, and an acid or phenol. The components are to be separated, their physical properties determined, their categories assigned, and one specific derivative prepared for each.
