Dehydrohalogenation reaction example

WebJan 23, 2024 · To synthesize alkynes from dihaloalkanes we use dehydrohalogenation. The majority of these reactions take place using alkoxide bases (other strong bases can also be used) with high temperatures. This combination results in the majority of the product being from the E2 mechanism. E2 Mechanism WebOct 10, 2024 · Dehydrohalogenation: A reaction in which a hydrogen atom and a halogen atom are removed from adjacent atoms in a molecule, forming (usually) an alkene or an alkyne. When reacted with strong base such as hydroxide ion, cyclohexyl chloride suffers dehydrohalogenation by a concerted E2 reaction mechanism (shown here).
