摘要

Pyridinium hydrobromide perbromide (PHPB) is a solid complex of pyridine with bromine which is used as a source of bromine. It is more convenient to use definite small amounts of active bromine with this stable reagent than with bromine itself. It had been employed for bromination of ketones, acetals, alkenes, activated phenols, anilines and heterocycles as well as oxidation/dehydrogenation reagent. 15 17. Yang , S.-H. 2009.
