Abstract

The focus on copper chalcogenide chemistry is experiencing continuous growth and interest over last few decades owing to their novel properties and significant applications in materials chemistry. The property of copper chalcogenides is mainly controlled by ch alcogen sources. For example, the recent works have also witnessed the active role of decade old ligand system imidazolin - 2 - chalcogenones for this endeavor. Notably, imidazolin - 2 - chalcogenon ligands have potential to serve as a ligand with copper in medici ne. Some other potential applications of these imidazolin - 2 - chalcogenone ligand supported copper included their use as precursor for nanomaterial synthesis and co - ligand in catalysis. However, these recent efforts have not answered the critical questions s uch as, do “homoleptic two coordinated” key intermediates exist in the catalytic process? How essential is “more π accepting imidazoline - 2 - selone” to isolate the homoleptic two coordinated coinage metal derivatives? In order to address these challenges , th is thesis deals with the t hree main aspects of Imidazolin - 2 - chalcogenones (ImC), su c h as (1) synthesis o f soluble copper(I) chalcogenone , (2) catalytic efficiencies of ImC ‒ Cu complexes , and comparison of catalytic activity of ImC‒Cu with NHC ‒ Cu (Chart A) . Indeed, twenty one new structurally interesting copper(I) chalcogenones have been isolated and characterized by CHN analysis, FT - IR, multinuclear NMR, TGA, UV - vis, and single crystal X - ray diffraction techniques. These new molecules are found to be very active catalysts in ‘cabon - boron ’ , ‘cabon - nitrogen’ and ‘carbon - silicon’ bond formation reactions.
