An Efficient and Green Procedure for the Synthesis of 2,4,6-Triarylpyridines Using PPA-SiO2 as a Reusable Heterogeneous Catalyst Under Solvent-Free Conditions
Silica gel-supported polyphosphoric acid (PPA-SiO2) was found to be highly efficient, eco-friendly and recyclable heterogeneous catalyst for the synthesis of 2,4,6-triarylpyridines through one-pot three-component reaction of acetophenone, aryl aldehydes, and ammonium acetate under solvent-free condi...
