mechanochemical approach towards 3,4-dihydro-2(1H)-quinolinones by catalysis with FeBr3 has been developed. The solvent-free processes start from readily available dioxazolones, which undergo intramolecular amidation reactions providing the products in good to very high yields. Practically, the reactions are easy to perform, proceed within a short period of time and require only standard ball milling equipment
