Reactions of Cycloalkanes

WebLike linear-chain alkenes, cycloalkenes have addition reactions on the double bond because they have higher energy and shorter length than a single bond or sigma (σ). The main reactions of the cycloalkenes are addition, but also exhibit reactions of oxidation, reduction and allylic halogenation. WebCycloalkenes and cycloalkynes are normally prepared from cycloalkanes by ordinary alkene‐forming reactions, such as dehydration, dehalogenation, and dehydrohalogenation. Typical preparations for cyclohexene and cyclohexyne are illustrated in Figure 2 .

4.2 Cycloalkanes and Their Relative Stabilities

Ring-Closing Metathesis switches out functional groups from one or multiple terminal alkenes to form a cycloalkene. This process can be used to form cycloalkenes of either E or Z configurations, depending on the stereochemistry of the second ring strain. Birch reduction is a possible method to reduce reduces aromatic compounds into cycloalkenes, specifically cyclohexadiene.
