Practical, mild and efficient electrophilic bromination of phenols by a new I(<scp>iii</scp>)-based reagent: the PIDA–AlBr₃system

Abstract

or isolated after centrifugation. Its stability at 4 °C after preparation was confirmed over a period of one month and no significant loss of its reactivity was observed. Additionally, the gram-scale bromination of 2-naphthol proceeds with excellent yields. Even for sterically hindered substrates, a moderately good reactivity is observed.
