Reactions such as the Diels-Alder reaction and al-dol condensations, which are important in synthetic and mechanistic organic chemistry, are of only minor importance when drug degradation is being considered. Pharmaceutical scientists need to refocus their attention on reactions such as hydrolysis, oxidation, photolysis, racemization, and decarboxylation, the routes by which most pharmaceuticals degrade.

Extensive collections of pK values are available in the literature, e.g., [98-101]. It is also possible to predict pK values for a broad range of organic acids and bases using linear free energy relationships based on a systematic treatment of electronic (inductive, electrostatic, etc.) effects of substituents which modify the charge on the acidic and basic center. Quantitative treatment of these effects involves the use of the Hammett Equation which has been a real landmark in mechanistic organic chemistry. A Hammett parameter (a), defined as follows ... 

The book concludes by providing an outlook on possible future development in this field. Researchers and practitioners engaged in active work on synthetic or mechanistic organic chemistry and its practical applications will find this text to be invaluable in both its scope and its depth. ... 

This is a book which, in my opinion, should find a place in the libraries of all universities and research institutes, where people are engaged in active research in synthetic or mechanistic organic chemistry. The task taken by the author was Herculean which the author has carried out with commendable skill, when he could bring in a reasonable amount of space, all the different aspects of ion-radical chemistry. The book is characterized by the lucidity of presentation, which has made it immensely readable (Asish De, Indian J. Phys. 11 A (4), 401, 2003).

Symmetry has for many years played a vital role in the elucidation of molecular structure although apart from some special situations it was not thought to have a dominant influence on the structure or chemical properties of molecules. In recent years however it has played a large part in the interpretation of many organic reactions through the work of Woodward and Hoffman, and the concept of symmetry allowed or forbidden reaction is now an important part of mechanistic organic chemistry. 

Whereas simple haloalkanes play a very important role in synthetic and mechanistic organic chemistry in the ground state, the interest in excited-state reactions centres more on polyhaloalkanes and on vinyl or aryl halides. Chloromethane absorbs only in the far ultraviolet (X-, . 173 nml, but ionger-wavelength absorption occurs for bromo- or iodo-cornpounds (CH, has A, 258 nrn and for polyhalo-compounds (iodoform, CHIj, has A, 349 nm and is coloured yellowi.

Lewis structures serve admirably for many aspects of mechanistic organic chemistry. Frequendy, however, we need a more accurate bonding model.

The clear different outcome for closely related systems is by itself very interesting, and further study to understand such newly discovered results is strongly desired to deepen and expand our knowledge in mechanistic organic chemistry.
