Abstract
Alkenyl halides, such as an alkenyl bromide or an alkenyl chloride, are produced by a process that includes a step of forming a reaction mixture containing an alkyl dibromide or a chlorobromoalkane and an allylmagnesium bromide and/or an allylmagnesium chloride, and then producing the alkenyl halide in the reaction mixture.
