Reaction-Map of Organic Chemistry Steven Murov
The Reaction-Map of Organic Chemistry has been designed to provide an overview of most of the reactions needed for the organic chemistry course and should help students develop synthetic routes from one functional group to another.

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.

Synthesis of Unsymmetrical Alkynes via the Alkylation of Sodium Acetylides. An Introduction to Synthetic Design for Organic Chemistry Students Jennifer N. Shepherd and Jason R. Stenzel
Teams of students design a microscale synthesis of an unsymmetrical alkyne using commercially available terminal alkynes and alkyl halides and characterize the resulting products using TLC, IR, and 1H NMR spectroscopy. Depending on the chosen reactants, students observe both substitution and elimination products, or in some cases, no reaction at all.

A study of the E2 reaction for the microscale organic lab Flash, Patrick; Galle, Fred; Radil, Mark
Students determine the pseudo-first-order rate constant for the elimination of HBr from 2-bromobutane and measure the yield and approximate composition of the alkene products, determine the yield of alkenes from 1-bromobutane under the same conditions, and examine the effect of changing solvent polarity on alkene yields for the two halides.

Aromatic substitution reactions: when you've said ortho, meta, and para you haven't said it all Traynham, James G.
The author presents a range of examples for nucleophilic, electrophilic, and free-radical reactions where the ipso is an important, predominant, or even exclusive site of reaction.

Organic lecture demonstrations of common-ion effect, ionizing power of solvents, and first-order reaction kinetics Danen, Wayne C.; Blecha, Sr. M. Therese
The hydrolysis of tert-butyl chloride is the basis of three demonstrations which each illustrate an important principle of organic chemistry: the common-ion or mass law effect, the effect of changing the ionizing power of a solvent on a solvolysis reaction, and the collecting and plotting of data to illustrate a first-order reaction.

A dynamic carbon model capable of showing changes in hybridization Fountain, K. R.
It is possible to construct a simple dynamic model of a carbon atom that demonstrates the Walden inversion, the SN1 reaction, and when joined with another units like itself demonstrates the full spectrum of elimination reactions.

Donor-acceptor interactions in organic chemistry Sunderwirth, S. G.
The purpose of this article is to aid teachers in making even more effective use of theoretical considerations in teaching organic chemistry; the primary objective is to emphasize the underlying principles that are common to the following four basic types of reactions: substitution, addition, elimination, and rearrangement.
