Aerobic oxidation of thiols to disulfides catalyzed by a manganese(III) Schiff-base complex

The oxidative coupling of aromatic thiols into the corresponding disulfides using a manganese(III) Schiff-base complex as catalyst under aerated and mild conditions is described. This system provides an efficient, convenient and practical method for the syntheses of symmetrical disulfides. (c) 2006 Elsevier B.V. All rights reserved.
