A mild, greener approach toward thioamide synthesis has been developed. Its unique features include water-mediated reaction with no input energy, additives, or catalysts as well. The presented protocol is attractive with readily available starting materials and the use of different array amines, along with a scaled-up method. Biologically active molecules such as thionicotinamide and thioisonicotinamide

A series of ruthenium, rhodium and iridium complexescontaining thioamide derivatives have been synthesized. In the presence of a counterion (NH4PF6) binuclear complexes were isolated, whereas in the absence of a counterion mononuclear complexes were obtained. The binuclear complexes exist as supramolecular structures by bridging the two metal centers through nitrogen and sulfur atoms of the two ligands

A novel thionation protocol for amide compounds, with the system rhodanine/secondary amine has been discovered. Clean and efficient synthesis of a variety of thioamides can be achieved through this simple and convenient method using MCM-41 mesoporous silica as an acid catalyst. For this purpose we have synthesized MCM-41 silica and characterized by using an array of sophisticated analytical techniques like BET, HR TEM, EDX, XRD, 29Si MAS NMR and FTIR. This reaction is therefore a very neat example of a functional group interconversion. (C) 2013 Elsevier Ltd. All rights reserved.
