A Convenient and Benign Synthesis of Sulphonamides in PEG-400

摘要

A simple and convenient method is reported for the synthesis of a series of sulphonamides in PEG-400 using potassium carbonate as the base. The reaction is carried out in a heterogeneous medium and consequently product recovery is simple. The desired products with a variety of aromatic amines could be synthesized in a short reaction time in good yield. The PEG could be recovered for reuse.
