Mz. Zhao et al., A NOVEL CHROMIUM TRIOXIDE CATALYZED OXIDATION OF PRIMARY ALCOHOLS TO THE CARBOXYLIC-ACIDS, Tetrahedron letters, 39(30), 1998, pp. 5323-5326
A novel CrO3 catalyzed oxidation of primary alcohols to the carboxylic
acids is reported. The oxidation proceeds smoothly with only 1-2 mol
% of CrO3 and 2.5 equivalents of H5IO6 in wet MeCN to give the carboxy
lic acids in excellent yield. No significant racemization is observed
for alcohols with adjacent chiral centers. Secondary alcohols are clea
nly oxidized to ketones. (C) 1998 Elsevier Science Ltd. All rights res
