Processes for the production of chlorinated and/or brominated propanes and/or propenes are provided. The present processes make use of a feedstream comprising 1,2-dichloropropane and at least one bromination step. Regioselectivities of at least 90% to desired dichlorobromopropanes are provided. The present processes may also include one or more halogen exchange and/or dehydrohalogenation steps that leverage the regioselectivities provided by the initial bromination step.
