摘要

N-Oxyl-mediated oxidation of alcohols was performed successfully in a disperse system with N-oxyl-immobilized silica gel as a disperse phase and aqueous NaOCl as a disperse media. Column-flow systems were also investigate as a new device for automated oxidation process; thus, simple operations, e. g., 1) adsorption of alcohol in the silica gel column, 2) treatment with aqueous NaOCl, 3) extraction with acetone, 4) evaporation of the solvents afforded the corresponding ketone in good yields.
