Abstract: Cetylpyridinium tribromide (CetPyTB) has been synthesized by a new environmentally benign protocol and its reactivity studied. Results show that the reagent shows efficiency as a brominating agent for electron-rich aromatic compounds as well as an efficient catalyst for acetylation of the alcohols . thus proving it to be a note-worthy addition to the existing organic tribromide reagents.
