Oxidation of alcohols with sodium periodate catalyzed by supported Mn(III) porphyrins

Abstract

The mild and efficient oxidation of alcohols with sodium periodate catalyzed by manganese(III) tetrakis(p-sulfonatophenylporphyrinato) acetate, [Mn(TPPS)], supported on polyvinylpyridine, [Mn(TPPS)-PVP], and Amberlite IRA-400, [Mn (TPPS)-Ad IRA-400], at room temperature is reported. The catalysts used in this study showed high activity not only in the oxidation of benzylic and linear alcohols but also in the oxidation of secondary alcohols at room temperature. These catalysts can be reused several times without significant loss of their activity.

Sulfonated palladium(II) N‐heterocyclic carbene complex immobilized on nano–micro size poly(4‐vinylpyridinium chloride) for Suzuki‐Miyauracross‐coupling reaction

“…In continuation of our previous work using supported catalysts in organic synthesis, here we report the preparation and characterization of the sulfonated palladium(II) NHC complex Pd II (NHC)SO 3 − , supported on poly(4‐vinylpyridinium chloride), as a heterogeneous catalyst in Suzuki‐Miyaura C–C coupling reactions (Scheme ).…”
