Highlights of the Collection

Nomenclature

• Acronyms: about 150 common acronyms are listed along with their full names and structures
• Named Reactions: This Web site lists 95 of the most important named reactions in organic chemistry. Each is linked to a Web page that gives the primary reference and equations for one or more recent literature examples that illustrate the use of the reaction.
• Named Reagents: This convenient list provides structures of more than 160 common reagents used in organic chemistry that are often referred to by the originator’s name, by an acronym, or by a trade name.
• Named Rules and Effects: Concise descriptions and structures of a number of named effects, rules, stereochemical models and hypotheses—from Baldwin’s rules to the Zimmerman–Traxler transition state—are given.

International Union of Pure and Applied Chemistry documents describing the nomenclature of organic compounds:

• Class Names
• Organic Compounds
• Physical Organic Terms
• Bioinorganic Terms
• Heterocycles
• Carbohydrates
• Steroids
• Stereochemistry

Many reactions of organic compounds involve reactive intermediates.

• Reactive intermediates:

NMR Spectroscopy

• Proton Chemical Shifts
• Carbon-13 Chemical Shifts
• NMR, IR, and Mass Spectra

pK_a Values

• Bordwell pK_a Values in DMSO:The late F. Bordwell of Northwestern University measured the pK_a values of thousands of organic compounds. This Web site makes some of the data he measured conveniently available to the chemical community, and provides literature references to the published data (the Web site also includes much unpublished data).
• Aqueous pKa Values: This list was originally collected by W. P. Jencks and F. H. Westheimer and compiled by R. Williams.
• Gas Phase Acidity: This site provides a very comprehensive collection of thermodynamic data selected by the scientists at the National Institute of Standards and Technology (NIST).
