Reusable Nanocatalyst: Zirconia and Sulfated Zirconia
International Letters of Chemistry, Physics and Astronomy, 2014 1,5-benzodiazepines have been synthesized by Nano Zirconia and Nano Sulfated Zirconia in solvent free conditions. Synthesis was carried out by conventional as well as microwave method. Benzodiazepines were synthesized by reacting o-phenylenediamine and few ketones in the presence of catalytic amount of Nanoparticles.
