Amines and Aniline pH of aqueous ammonia, cyclohexylamine, and aniline, iodination of aniline, oxidation of aniline with benzoyl peroxide, the nitrous acid test, diazo coupling, reaction of luminol and light sticks are demonstrated.
Exploding Soap Bubbles: Hydrogen + Oxygen A series of three videos shows that as the ratio of oxygen to hydrogen in soap bubbles increases, the explosions that occur when the bubbles are ignited get louder. (The fact that with an excess of oxygen the explosions would become softer again is not shown.) Each video is repeated with no voice-over so that only the sounds of the explosions are heard. Five still images are provided to show the stoichiometry on the molecular scale. The videos are intended to be shown in order beginning with Hydrogen Alone and ending with hydrogen plus more oxygen.
Synthesis of Albendazole Metabolite: Characterization and HPLC DeterminationGraciela Mahler, Danilo Davyt, Sandra Gordon, Marcelo Incerti, Ivana Núñez, Horacio Pezaroglo, Laura Scarone, Gloria Serra, Mauricio Silvera, and Eduardo Manta In this laboratory activity, students are introduced to the synthesis of an albendazole metabolite obtained by a sulfide oxidation reaction. Albendazole as well as its metabolite, albendazole sulfoxide, are used as anthelmintic drugs. The oxidation reagent is H2O2 in acetic acid. The reaction is environmental friendly, fast, and proceeds with high yield. The crude reaction is analyzed by HPLC chromatography to determine purity. The simplicity of the experiment allows students to study chiral concepts, physicochemical and spectroscopic properties of the compounds, and HPLC determinations.

Cocrystal Controlled Solid-State SynthesisMiranda L. Cheney, Michael J. Zaworotko, Steve Beaton, and Robert D. Singer Describes experiments that can easily be adapted to a typical undergraduate organic chemistry course and are inexpensive, relatively safe, require little or no solvent, have high atom economy, make use of non-toxic or low toxicity compounds, and generate negligible quantities of waste.

The Synthesis of a Cockroach PheromonePatty L. Feist This paper describes the synthesis of gentisyl quinone isovalerate or blattellaquinone, a sex pheromone of the German cockroach and a compound with real-world applications. The experiment also affords students practice in extraction as well as IR and NMR spectroscopy. Feist, Patty L. J. Chem. Educ.2008, 85, 1548.
