2 Cross-References to Redox Reactions Already Discussed in Chapters 1-16 

Many reactions that fit the definition of an organic chemical redox reaction (Section 17.1) have already been presented in Chapters 1-16. The presentation of these reactions in various other places—without alluding at all to their redox character—was done because they follow mechanisms that were discussed in detail in the respective chapters or because these reactions showed chemical analogies to reactions discussed there. Tables 17.3 and 17.4 provide cross-references to all oxidations and reductions discussed thus far. 

The plethora of entries in Tables 17.3 and 17.4 emphasizes that organic chemical redox reactions are not limited to one mechanism and are not even based on a small number of mechanistic principles. Hence, one should not expect any mechanistic homogeneity among the reactions to be discussed in Chapter 17. Sections 17.3 (oxidations) and 17.4 (reductions) are thus not organized on the basis of mechanistic considerations. Instead, the ordering principle reflects preparative aspects Which classes of compounds can be oxidized or reduced into which other classes of compounds, and how can these transformations be accomplished  

1 Oxidations in the Series Alcohol — Aldehyde — Carboxylic Acid 

For the oxidation of primary or secondary alcohols on a laboratory scale, one usually employs one of the reagents listed in Table 17.5. The reactivity of these six reagents toward alcohols and aldehydes can be summarized as follows
