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.

Monitoring the Rate of Solvolytic Decomposition of Benzenediazonium Tetrafluoroborate in Aqueous Media Using a pH Electrode  Floyd L. Wiseman
This article discusses the use of pH electrodes to monitor the aqueous solvolysis of the benzenediazonium ion and shows that the results are in reasonable agreement with literature values.

Microscale Synthesis of 1-Bromo-3-chloro-5-iodobenzene: An Improved Deamination of 4-Bromo-2-chloro-6-iodoaniline  Michael W. Pelter, Libbie S.W. Pelter, Dusanka Colovic, and Regina Strug
Overall, we find this procedure to be advantageous to the published methods owing to its requirement of less starting material, higher product yields, and a greatly simplified procedure.

The synthesis of methyl salicylate: Amine diazotization.  Zanger, Murray; McKee, James R.
Unlike many organic chemistry labs, this experiment does not expose students to carcinogenics, nor does it smell bad.
