摘要

The copper-catalyzed intramolecular N-arylation of 2-bromoarylureas performed in water leading to the benzo [d] imidazolone framework is reported. The scope of the methodology presented herein proved to be broad and afforded a significant number of benzoimidazolones in good to excellent yields. The reported protocol is based on the use of CuI and TMEDA acting both as the ligand and as the base in a water solution, which ...
