Description:
Glutathione, a completely benign ubiquitous tripeptide, has been used as a reducing agent for the expeditious synthesis of various metal nanoparticles including Ag, Au, Pd and Pt under microwave irradiation conditions in less than one minute. The particles sizes were found to be in the range 5-100 nm depending on the reaction conditions. The effect of microwave power and other reaction conditions on the morphology of the nanoparticles has been studied. The role of glutathione as a magnetically separable organocatalyst for the Paal-Knorr reactions with excellent yield (> 90%) and reusability (up to 5 times) has also been demonstrated by anchoring it to the surface of magnetic nanoparticles
