Here, we report a quick, convenient, and green ultrasound-assisted synthesis of thiourea derivatives by condensation between available aliphatic amines and carbon disulfide in water and polyethylene glycol under ultrasound irradiation. The methodology affords both unsymmetrical and symmetrical thiourea derivatives without tedious workup in good yield.
