Abstract
Photooxidation of dialkyl and alkyl aryl sulfides to the corresponding sulf oxides with clay-bound methylene blue is studied in acetonitrile. A signifi cant increase in sulfoxide/sulfone ratio and a marginal increase in cooxida tion of a second sulfide molecule are observed. The results are explained i n terms of a suitable mechanism involving persulfoxide and thiadioxirane in termediates. (C) 2001 Elsevier Science Ltd. All rights reserved.
