Abstract:

A column padding silica gel was used to support 2,2,6,6-tetramethylpiperdine-1-oxyl (TEMPO) and to adsorb NOx to provide an oxidant system for the selective oxidation of alcohols. A wide range of alcohols were oxidized to the corresponding aldehydes and ketones with high selectivities and conversions using this heterogeneous catalyst under mild conditions.
