| Résumé : |
"These volumes contain reviews of methods which are applied to the determination of reaction rates and mechanisms. This is a "Second Completely Revised and Augmented Edition." This new edition contains 27 chapters, each of which considers some aspect of the subject. Since there is a different author for each chapter, the writing style and the type of material included varies greatly. For example, one author will carefully state the limits of applicability of s derivation and the next may give a dogmatic statement,. An author whose chapter appears later in the book may not refer back on. previous chapter. For example, the discussion of the transition state theory occurs at least twice. The discussions of the acidity function are mother instance of lark of careful editorial work. On page 522, "The success of the diagnostic use of the acidity function.. . has been striking," and on 1463, "The conflicting evidence and doubts … somewhat diminish its value as a diagnostic criterion." The last two quotes certainly indicate a difference of opinion between "experts" in the field. The unwary reader who has had little experience with acidity functions could be misled by rending the first, optimistic statement with no reference to the second. One additional objection is that the second edition repeats four or five chapter from the first edition. These are essentially unchanged, and add considerably to the cost of the book. The contents of these volumes are too diverse to comment upon in detail. The expansion has been largely in the field of Rapid and Very Rapid Reactions. Chapters 15 to 20 include a discussion of Relaxation Methods, Flash Photolysis, Magnetic Resonance Methods, Electrochemical Methods and Photostationary Methods. The study of non-kinetic methods has been somewhat less fully expanded in the discussions of thermodynamics, product criterion of mechanism, evidence for the formation of intermediates in organic reactions, use of isotopes, and tagged groups, stereochemistry and mechanism. These chapters contain many examples of mechanistic criteria that may be used; as well as 8, discussion of their limits. Krevoy's conclusion, "None of the methods of determining mechanism outlined in this chapter is completely reliable," and Saunders' topic, Pitfalls of Tracer Work, illustrate the care used by these authors to evaluate these techniques. The chapter on the interpretation of rate data. is also new. This discussion covers practical aspects of determining rate constants and the data that may be derived from these. The second part includes the general questions of linear free energy relationships, e.g., the Hammett equation, the Taft equation, etc. The Iast part presents an analysis of classic experiments in which the "new factor," the effect of structure on reactivity, was discovered. This carefully written chapter is well worth the consideration of the practicing organic chemist. To summarize, these volumes contain much valuable information for the organic chemist. The convenient summary of data and idem by the experts in the field outweighs the editorially uneven quality of the final product." |
