Frank Westheimer's Early Demonstration of Enzymatic Specificity Addison Ault
Reviews one of the most significant accomplishments of one of the most respected chemists of the 20th centurya series of stereospecific enzymatic oxidation and reduction experiments that led chemists to recognize enantiotopic and diastereotopic relationships of atoms, or groups of atoms, within molecules.

Nucleophilic Addition vs. Substituion: A Puzzle for the Organic Laboratory Ernest F. Silversmith
The chemistry of beta-carbonyl compounds is studied. Beta-carbonyl compounds react with hydrazines to give products with a 5-membered ring containing two nitrogens. The experiment makes students determine whether ethyl 2-acetyl-3-oxobutanoate reacts like a beta-diketone or like a beta-keto ester.

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.
