Review of General Chemistry
Cyclohydrocarbons
Cycloalkanes can be prepared by ring-cyclization reactions, such as a modified Wurtz reaction or a condensation reaction. Additionally, they can be prepared from cycloalkenes and cycloalkynes (Figure

Cycloalkenes 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
