bromochlorination of styrene derivatives with tetrabutylammonium dichlorobromate(1−) (1) in such protic solvents as acetic acid and methanol gives the corresponding bromo chloro adducts along with substantial amounts of solvent-incorporated products in a regiospecific manner (regioselective in the case of 3-nitro- or 2-chlorostyrenes). The reaction of 1-phenylpropenes with 1 gives nonstereospecific but regiospecific
