A recyclable and high bromine containing di-(tribromide) reagent, hexamethonium bis
(tribromide)(HMBTB) has been synthesized and utilized for the bromination of various
organic substrates. The spent reagent hexamethonium bromide (HMB) can be effectively
recycled by regenerating and reusing it without significant loss of activity. The crystalline and
stable bis (tribromide) is an effective storehouse of very high percentage of active bromine
requiring just half an equivalent of it for complete bromination. Both the Br 3− moieties in …
