a mixture of TEMPO, Oxone and tetraethylammonium bromide. The process proceeds first through the oxidation of the alcohol to the ketone, followed by dibromination of the alkene with bromine that is generated from Oxone and tetraethylammonium bromide. Quenching the reaction with triethylamine then facilitates an elimination and forms the vinylbromide. The presence of electron-donating groups on the
