摘要:
Optically active (salen)Mn(III)Cl complexes are effective catalysts for the oxidation of sulfides to sulfoxides with modest enantioselectivity. An optimal reaction system consisting of unbuffered hydrogen peroxide as the stoichiometric oxidant, acetonitrile as solvent, and 2-3 mol% of complex 1 effects conversion of aryl sufides to sulfoxides in 84-95% isolated yield, and 34-68% ee.
