【 摘 要 】

The oxidation of secondary alcohols into corresponding ketones has been described using heterogeneous nanocrystalline TiO2 as catalyst at a moderate temperature with quantitative yields. Use of H2O2 instead of O2 (g) is the main feature of our methodology since maintenance of PO2 (g) at elevated temperature is not easy. Besides, this catalyst could be recovered and reused for further reactions with consistent activity. Hence, our present protocol is economical and throughout clean consisting of green reagent, solvent, and catalyst.
