Synthesis of di/trimeric substituted pyrazolium salts was carried out under a conventional/solvent‐free silica‐supported muffle furnace method. The solid phase method observed remarkable response compared with the conventional method for the preparation of pyrazolium salts. Di/trimeric substituted pyrazolium salts acted as a very good catalyst for benzilic acid preparation while compared with existing literatures.
