Such reactions are novel, occur under mild conditions and give NHCs in high yield and purity. This phenomenon was studied using various spectroscopic techniques and control experiments with elemental sulfur. Quantum chemical calculations were employed to provide a deeper understanding of such transformations.  ISSN : 2046-2069  Journal Name : RSC ADVANCES  Volume : 3  Issue Number : 6  Publishing Year : 1434 AH 2013 AD  Article Type : Article  Added Date : Thursday, July 20, 2017  Researchers Researcher Name (Arabic) Researcher Name (English) Researcher Type Dr Grade Email D Jishkariani Jishkariani, D Researcher     c (Hall (Hall, c Researcher     A Oliferenko Oliferenko, A Researcher     b Tomlin Tomlin, b Researcher     p Steel Steel, p Researcher     A Katritzky Katritzky, A Researcher     Files File Name Type Description  42122.pdf pdf   Back To Researches Page
