Sulfated zirconia as an efficient catalyst for organic synthesis and transformation reactions

Sulfated zirconia as an efficient catalyst for organic synthesis and transformation reactions The efficacy of sulfated zirconia catalyst was investigated towards various acid-catalyzed organic syntheses and transformation reactions in the liquid phase. The SO42−/ZrO2 efficiently catalyzes the synthesis of 1,5-benzodiazepines, bis(indolyl)methanes, diaryl sulfoxides 3,4-dihydropyrimidinones and tetrahydropyranylation of alcohols and phenols.
