Abstract
A convenient method for the preparation of [4-hydroxy-TEMPO + NaCl]/SiO2 was developed. And [4-hydroxy-TEMPO + NaCl]/SiO2 with Fe(NO3)3·9H2O was used for an aerobic oxidation of alcohols to carbonyls under mild reaction conditions. Alcohols were converted to the corresponding carbonyls in good to excellent yields. [4-Hydroxy-TEMPO + NaCl]/SiO2 can be easily separated from the reaction mixture by filtration and reused at least six times.

- 18 The content of water was estimated by weight difference between [4-hydroxy-TEMPO + NaCl]/SiO2 and [4-hydroxy-TEMPO + NaCl]/SiO2 which was dried at 160 °C under reduced pressure (8 mmHg) for 3 h
- 19 Aerobic Oxidation of Alcohols A mixture of alcohols (2.0 mmol), Fe(NO3)3·9H2O (5–8 mol%) and [4-hydroxy-TEMPO + NaCl]/SiO2 [(0.1 + 0.1) mmol/g, 1.0 g] was stirred in DCE (5 mL) under air (1 atm) at r.t., and then the used supported reagent were removed by filtration. Product yield was determined by GLC analysis using n-dodecane as internal standard
