We present here an efficient and simple method for the N-alkylation of aromatic cyclic imides employing cesium carbonate as the base in anhydrous N,N-dimethylformamide at low temperatures (20-70 ËC). The employment of microwave irradiation presents noteworthy advantages over conventional heating. The method is compatible with base labile functional groups.
本文介绍了一种高效且简便的方法,通过在低温(20-70℃)无
