ABSTRACT:
Primary and/or tertiary allyl halides are prepared by reaction of a hydrogen halide (e.g. hydrogen chloride) with a terminal conjugated diene (e.g. myrcene, .beta.-farnesene, .beta.-springene or 15-chloro-.beta.-springene) in the presence of, as catalyst, a cuprous halide together with a quaternary ammonium salt or a phosphonium salt containing at most 16 carbon atoms, or a salt of a tertiary amine containing at most 10 carbon atoms, the reaction being carried out in an organic solvent in which the catalyst complex is soluble.
