Xu, Haiyan published the artcileDABCO as a practical catalyst for aromatic halogenation with N-halosuccinimides, Quality Control of 91-16-7, the publication is RSC Advances (2022), 12(12), 7115-7119, database is CAplus and MEDLINE.
A simple and practical synthetic approach for synthesis of aromatic halides was developed. Simple Lewis base, DABCO, was used as the catalyst. This arene halogenation process proceeded conveniently and efficiently at ambient conditions, providing the desired products in good to excellent yields and selectivity.
