Versatile Methods for the Synthesis of Si(OR)3-Functionalised Imidazolium Salts, Potential Precursors for Heterogeneous NHC Catalysts and Composite Materials

Versatile methodologies for the synthesis of N-alkyl and N-aryl, and alkoxysilyl-functionalised mono- and bis-imidazolium salts are discussed. Such salts could find applications for heterogeneous N-heterocyclic catalysts and sol-gel materials.
