Silylene Supported Ni Complex and Its Catalytic Application in C-N Coupling Reactions

Abstract

The chemistry of N-heterocyclic silylenes (NHSis) [a higher analogue of NHC], is one of the hottest research topics in current low-valent organometallic chemistry. In this work, a hybrid N-heterocyclic silylene (NHSi) and phosphine-based compound was developed and used as a ligand in transition metal-catalyzed homogeneous catalysis. We will be discussing the development and electronic as well as steric properties of silylenes especially NHSi ligands to achieve the potential catalyst for transition metal-catalyzed organic transformation. The electronic and steric properties of the newly synthesized silylene- and phosphine-based hybrid ligand are described. Further, the application of the ligand-supported NiII complex in the C-N coupling reactions as potent catalyst is described. Next section will cover the synthesis and characterization of the NHSi and phosphine-based ligand and its NiII metal complex.
