Abstract
The sol-gel entrapment of chromium(VI) within a silica matrix; obtained by oxidation with ozone of the corresponding entrapped chromium(III), was foun d to be an efficient and recyclable oxidizing system (at least up to 16 tim es) for benzylic alcohols. No leaching of chromium in solution was observed , which prevented any environmental pollution. (C) 2001 Elsevier Science Lt d. All rights reserved.
