Many organic chemistry textbooks discuss the synthesis of a functional group and the reactivity of that group sequentially, but these two groups of reactions generally have little to do with one another. Instead, when I discuss a functional group’s reactivity, I cover the synthesis of compounds that are formed as a result of that reactivity, often by having students design syntheses. In Chapter 6, for example, students learn about the reactions of alkenes, but they do not learn about the synthesis of alkenes. Instead, they learn about the synthesis of alkyl halides, alcohols, ethers, epoxides, alkanes, etc.—the compounds formed when alkenes react. The synthesis of alkenes is not covered until the reactions of alkyl halides and alcohols are discussed—compounds whose reactions lead to the synthesis of alkenes. This strategy of tying together the reactivity of a functional group and the synthesis of compounds resulting from its reactivity prevents the student from having to memorize lists of unrelated reactions. It also results in a certain economy of presentation, allowing more material to be covered in less time. Although memorizing different ways a particular functional group can be prepared can be counterproductive to enjoying organic chemistry, it is useful to have such a compilation of reactions when designing multistep syntheses. For this reason, lists of reactions that yield a particular functional group are compiled in Appendix III. In the course of learning how to design syntheses, students come to appreciate the importance of reactions that change the carbon skeleton of a molecule; these reactions are compiled in Appendix IV.
