1,2-Dibromohexane is a haloalkane with the chemical formula C₆H₁₂Br₂. It is a colorless liquid with a relatively high boiling point (90 °C).

Synthesis and reactions

1,2-Dibromohexane can be prepared by the bromination of 1-hexene. Elemental bromine and 1-hexene react together in an inert solvent to give 1,2-dibromohexane in high yields.

1,2-Dibromohexane can be used to synthesize 1-hexyne by reacting it with potassium hydroxide in triethylene glycol in a dehydrohalogenation reaction.^[1] Alternatively, it also reacts with sodium amide in ammonia to yield 1-hexyne.^[3]
