Abstract
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 Br3− moieties in HMBTB are nearly linear with Br–Br–Br angle of 179.55°.
