- Also behaves as a source of positive bromine. Electron-rich aromatic compounds undergo uncatalyzed ring-bromination: Tetrahedron Lett., 38, 4415 (1997). The bromination of less active substrates can be catalyzed by TMS triflate. Bromination of aromatic rings, including those with electron-withdrawing substituents, also occurs in the presence of strong acids: Bull. Chem. Soc. Jpn., 67, 1918 (1994). Has also been used as an alternative to NBS for the ring bromination of activated benzoic acids in the presence of aqueous NaOH: Tetrahedron Lett., 34, 931 (1993).
