Abstract
A variety of symmetrical N,N'-disubstituted thioureas have been prepared by a simple reaction of amines and carbon disulfide on the surface of alumina under solvent-free microwave irradiation.

The development of simple and eco-friendly synthetic procedures constitutes an important goal in organic synthesis
A variety of symmetrical N,N'-disubstituted thioureas have been prepared by a simple reaction of amines and carbon disulfide on the surface of alumina under solvent-free microwave irradiation
As a part of our program to develop green synthetic procedures through surface-mediated solid phase reaction initiated a decade ago,[2] we report here an efficient synthesis of symmetrical N,N'-disubstituted thioureas by a simple reaction of carbon disulfide and amine on the surface of alumina under microwave irradiation (Scheme 1)
Summary
The development of simple and eco-friendly synthetic procedures constitutes an important goal in organic synthesis. Abstract A variety of symmetrical N,N'-disubstituted thioureas have been prepared by a simple reaction of amines and carbon disulfide on the surface of alumina under solvent-free microwave irradiation.
