A process for the simultaneous production of bromostyrene or dibromostyrene and of an alkyl bromide, which comprises reacting bromoethyl bromobenzene or bromoethyl dibromobenzene with an alkanol at an elevated temperature. When only these reactants are reacted, the temperature is between 400.degree.C and 550.degree.C; when the reaction is effected in the presence of a source of free radicals, the temperature used can be lower, and temperatures of about 300.degree.C are adequate.

Production of bromostyrene, dibromostyrene and alkyl bromides

A process for the production of mono-, di-, and/or tribromostyrene which comprises reacting .beta.-bromomethyl-mono-, di- and/or tribromobenzene at a temperature between 280.degree.C to 470.degree.C in the presence of a free radical source and either a lower alkanol or water.
