Abstract
One pot reaction of benzoyl isothiocyanate and Tris(hydroxy- methyl)aminomethane (Tris) at room temperature with polyethylene glycol-400 (PEG-400) as solid–liquid phase-transfer catalyst produced substituted N-benzoylthioureas with high yield. A reasonable pathway for their formation has been suggested.
