Solid-Supported Synthesis of Flexible Dimeric Pyridinium Salts and Their Catalytic Activities

Abstract

The synthesis of flexible dimeric pyridinium ionic liquids by both conventional and solid-supported approaches are described. We have optimized the Biginelli reaction with various concentrations of our synthesized ionic liquids with various counter ions. Among these, bromide-containing ionic liquids showed best catalytic activity.

Key words

ionic liquid - o-alkylation - solid supported - Biginelli reaction
