A simple, efficient and selective α-monobromination for arylacenones under solvent-free condition

摘要

The α-bromination reaction of arylacenones with 1,2-dipyridiniumditribromide-ethane (DPTBE) as brominating agent under solvent-free condition, selectively gave the corresponding α-bromoarylacenones derivatives with a simple procedure and excellent yields.
