Elemental Sulfur-Mediated Aromatic Halogenation. | LitMetric

Elemental Sulfur-Mediated Aromatic Halogenation.

J Org Chem

School of Pharmaceutical Sciences, Kindai University, Higashi-Osaka, Osaka 577-8502, Japan.

Published: January 2024

A method for aromatic halogenation using a combination of elemental sulfur (S) and -halosuccinimide has been developed. A catalytic quantity of elemental sulfur (S) with -bromosuccinimide (NBS) and -chlorosuccinimide (NCS) effectively halogenated less-reactive aromatic compounds, such as ester-, cyano-, and nitro-substituted anisole derivatives. No reaction occurred in the absence of S, underscoring its crucial role in the catalytic activity. This catalytic system was also applicable to aromatic iodination with 1,3-diiodo-5,5-dimethylhydantoin.
