1,3-Dibromopropane is a halogenated hydrocarbon. When at room temperature, it is a colorless to light-brown liquid. Synthetically, it is very useful to form C3-bridged compounds such as through C-N coupling reactions.
1,3-Dibromopropane was used in the first cyclopropane synthesis in 1881, the Freund reaction.[2]
1,3-Dibromopropane can be prepared via the free radical addition between allyl bromide and hydrogen bromide.[3]
