Chemistry of N Heterocyclic Carbene

N-Heterocyclic carbenes (NHCs) have received much attention in recent years both in main group synthesis and catalysis, due to their strong ¿-donating properties. Here, in the present work we have demonstrated the synthesis of NHC supported magnesium and zinc (II) bis(amide) complexes and their catalytic activity towards various organic reactions such as C-N bond formation reaction of amines with carbodiimides and cross dehydrogenative coupling reactions of amines with silanes have been studied. Apart from being used as an excellent neutral ligand system for stabilization of unusual molecules across the periodic table, the strong nucleophilicity of NHC makes its own place as a reagent, in synthesizing varieties of organic molecules. Here, we have presented a synthetic way to zwitterions, or "NHC-CDI" adducts. Continuing the synthesis of ligand system, a library of "NHC-CDI" adducts have been synthesized and their coordination behavior with main group elements, especially with magnesium and zinc has been studied.
