Application
Aerobic Oxidation of Alcohols Using 4-Hydroxy-TEMPO Adsorbed on Silica Gel
Typical Procedure:
Preparation of [4-hydroxy-TEMPO + NaCl]/SiO2
Silica gel (9.77 g) is added to the solution of 4-hydroxy-TEMPO (0.17 g) and NaCl (0.06 g) in water (50 mL), and the mixture is stirred at room temperature for half an hour. The water is removed by rotary evaporator under reduced pressure (65 °C and 40 mbar).
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] is stirred in DCE (5 mL) under air (1 atm) at room temperature, and then the used supported reagents are removed by filtration. Product yield is determined by GLC analysis using n-dodecane as an internal standard.
