TiO2ZrO2 composite: Synthesis, characterization and application as a facile, expeditious and recyclable catalyst for the synthesis of 2-aryl substituted benzoxazole derivatives

A new, green and sustainable approach for the synthesis of 2-substituted benzoxazoles by using a one-pot condensation reaction of 2-amino phenol and substituted aromatic aldehydes, catalysed by TiO2ZrO2 has been reported. The remarkable advantages of this method are the efficiency, high yields with less reaction time, mild reaction conditions, clean product profile, ease of preparation of inexpensive and environmentally friendly catalyst, ease of product isolation and cost efficiency. These expedient changes made this approach an interesting alternative to the existing methods.278
