Synthesis, catalysis and theoretical investigations on Ru(II) and Ru(III)-NHC complexes

Abstract

The investigation embodied in the thesis entitled “SYNTHESIS, CATALYSIS AND THEORETICAL INVESTIGATIONS ON Ru(II) AND Ru(III)-NHC COMPLEXES” was initiated in July 2018 in the Department of Chemistry, Indian Institute of Technology Indore. The objectives of this thesis are synthesizing new Ru(II)-NHC complexes bearing the protic and classical NHC in one molecule and study their structural electronic and catalytic application. The theoretical investigation on Ru(III)-NHC precursor complexes utilized in the synthesis of Ru(II)-NHC complexes. The focal points of the thesis are as follows- 1) Design and synthesis of ligands precursors having possibility of protic- and classical-NHC in one molecule. 2) Synthesis of transition metal complexes with CNC-pincer ligand platform having protic- and classical-NHC in same molecule. 3) To compare the structural and electronic properties of protic & classical-NHC and compare the catalytic activity of complexes. 4) Theoretical investigations on our synthetic work of Ru(III)-NHC complexes.
