A new N-heterocyclic catalyst system which contains N-heterocyclic carbene and amido as ligands, which are strongly bound to a palladium metal. Another heteroatom functionality can be used as a third ligand L. The NHC-amidate ligand system is unique in structure, and shows excellent reactivities in a number of chemical reactions. The chemical reactions include carbon-carbon and carbon-heteroatom (oxygen and nitrogen) bond formations, and oxidation reactions of saturated carbon chemicals via C—H activation.

A simple and efficient one-pot, three-component method has been developed for the synthesis of α-aminonitriles. This Streckerreaction is applicable for aldehydes and ketones with aliphatic or aromatic amines and trimethylsilyl cyanide in the presence of a palladium Lewis acid catalyst in dichloromethane solvent at room temperature.
