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.

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.

Hollow‐sphere catalysts were prepared by means of 3D network formation between a tetraimidazolium building block and palladium acetate. The bis(N‐heterocyclic carbene)–palladiumspecies that were concomitantly formed during growth of the hollowspheres showed excellent activity as heterogeneous catalysts in one‐pot three‐component Streckerreactions of ketones (see picture; TMS=trimethylsilyl).

A straightforward, mild, efficient, and general method has been developed for the synthesis of alpha-aminonitriles via Strecker reaction starting from aldehydes or ketones, amines, and trimethylsilyl cyanide in the presence of sulfated tungstate as a heterogeneous mild solid acid catalyst at room temperature and solvent free condition. The developed method has been successfully applied for the synthesis of a wide range of alpha-aminonitriles with variable functionality. (C) 2011 Elsevier Ltd. All rights reserved.
