- Darzens halogenationHalogenation Darzens halogenation is the chemical synthesis of alkyl halides from alcohols via the treatment upon reflux of a large excess of thionyl chloride or thionyl bromide (SOX2) in the presence of a small amount of a nitrogen base, such as a tertiary amine or pyridine or its corresponding hydrochloride or hydrobromide salt.
- Hell–Volhard–Zelinsky halogenationHalogenation The Hell–Volhard–Zelinsky halogenation reaction is a chemical transformation that transforms an alkyl carboxylic acid to the α-bromo derivative.
- Alkyne via solid-liquid phase-transfer catalyzed dehydrohalogenation: acetylene dicarboxaldehyde tetramethyl acetal and acetylene dicarboxaldehyde dimethyl acetalHalogenation
- Alkynes via phase transfer–catalyzed dehydrohalogenation: propiolaldehyde diethyl acetalHalogenation
