Pyrolysis of Aryl Sulfonate Esters in the Absence of Solvent: E1 or E2? A Puzzle for the Organic Laboratory John J. Nash, Marnie A. Leininger, and Kurt Keyes
An aryl sulfonate ester is synthesized and then pyrolyzed at reduced pressure. The volatile products are analyzed using gas chromatography to determine whether the thermal decomposition occurs via an E1 or E2 mechanism.

Semiempirical and DFT Investigations of the Dissociation of Alkyl Halides Jack R. Waas
Enthalpy changes corresponding to the gas phase heats of dissociation of 12 organic halides were calculated using two semiempirical methods, the HartreeFock method, and two DFT methods. All five methods agreed generally with the expected empirically known trends in the dissociation of alkyl halides.

Project for problem-oriented undergraduate organic or integrated undergraduate laboratory Silveira, Augustine, Jr.
This paper reports on an open-ended project which allows a great degree of flexibility in the laboratory. The project provided about a 6-week study for groups of 24 students each.
