• Selective monobromination of anilines, predominantly at the para-position, can be effected in THF: Synth. Commun., 23, 855 (1993). In aqueous AcOH, alkyl aryl ethers are p-brominated in high yield: Synth. Commun., 28, 499 (1998), whereas aryl methyl ethers are demethylated on heating in xylene: Indian J. Chem., 33B, 288 (1994).

• Stable, crystalline, readily-handled source of bromine, useful for a wide range of brominations, including ɑ-bromination of ketones: J. Am. Chem. Soc., 70, 417 (1948), and conversion of alkenes to vic-dibromides. See, for example: Org. Synth. Coll., 5, 604 (1973), Note 2. The rate of addition to alkenes increases markedly on increased substitution, so that selective bromination of the more substituted of two double bonds can be achieved: Synthesis, 966 (1979).
• In pyridine, cyclopentenones are converted directly to their ɑ-bromo derivatives (addition-elimination): Synth. Commun., 18, 1323 (1988).
