Abstract:

N-Heterocyclic Carbenes (NHC) present a viable alternative to traditional phosphine ligands in a variety of organometallic mediated catalytic reactions. Singlet ground-state carbenes are stabilized by the push-pull presence of two adjacent nitrogen atoms in an imidizolium 5-membered ring, allowing neutral electron donor properties. The ability to synthesize a variety of NHC ligands with differing steric and electronic properties is possible by changing the sustiuents on the nitrogen atoms of the imidizolium. Tunable characteristics and enhanced chemical and thermal stability give NHC’s an adva

Abstract:

Recent studies of new metal complexes for antitumor properties have focused on the speeding up of the treatment process in chemotherapy. In this study, focus was put on the two new metal complexes, copper (LCu(OAc)2) and iron {LFeCl2[FeCl4]}complexes that have been synthesized. Both new complexes have been characterized by FT-IR and UV-Vis. In addition, the structures of two complexes have been established by the X-ray crystallography. The molecular structures of (LCu(OAc)2) and LFeCl2[FeCl4] have been determined confirming that the ligand is bidentate (N,N) imidazopyridine and adopted octahed

This thesis describes the synthesis of new N-heterocyclic carbene complexes through the synthesis of 1,4-bis-substituted imidazolium salts or tricyclic saturated imidazolium salts. The introduction highlights some of the most successful methods for preparing N-heterocyclic carbenes and corresponding metal complexes. Examples of the use of these complexes in transition metal-catalysed processes are provided towards the end of this chapter. The second chapter is dedicated to our efforts to synthesize 1,4-bis-substituted imidazolium salts as precursors for the synthesis of N-heterocyclic carbene
