Covalently Anchored Polymer Immobilized Co(II) Phthalocyanine as Efficient Catalyst for Oxidation of Mercaptans using Molecular Oxygen as Oxidant

Abstract

The present paper describes the covalent immobilization of cobalt phthalocyanine “MEROX catalyst” to polystyrene resin via sulfonamide linkage and its catalytic activity for the oxidation of mercaptans to disulfides using molecular oxygen as an oxidant under alkaline conditions. Polymer-supported cobalt phthalocyanine, wherein the catalyst is chemically bounded to the support which prevents the leaching of the catalyst/ligand, can readily be recovered from the reaction mixture and reused for several runs without significant decrease in catalytic activity.

Synthesis, characterization and catalytic activity of peripherally tetra‐substituted Co(II) phthalocyanines for cyclohexene oxidation

“…Such prospective applications give a strong motivation to characterize and study the electronic structure and morphology of cobalt(II) phthalocyanine thin films since these determine the performance of devices. Moreover, the accurate assignment of the valance band and empty‐state electronic features is of central importance for the profound understanding of this material and its interfaces with different substances …”

Catalytically Active Systems of Cobalt Complexes with Wa-ter-Soluble Phthalocyanines

“…Even though chemical activation of the polymer allows efficient controlling set of formed functional groups within its structure upon catalyst's obtainment, [102] the method is not appropriate enough from technological point of view. Plasma treatment is one of prospective ways of polymer's modification.…”
