Polymer-supported metal complex oxidation catalysts
Bbstract Recent developments involving polymer-supported metal complexes as catalysts in oxidation reactions, using dioxygen, hydrogen peroxide, alkyl hydroperoxides, hypochlorite anion and iodosobenzene as oxidants are reviewed. binding of dioxygen, and in catalysis, along with the structurally closely related metallo-phthalocyanines, oxidative polymerization catalysed by polymer-supported cop...
متن کاملSelective and stable adhesion of Yeast cells to Boronate-containing Polymer Grafted to glass Supports
A series of sorbents containing various amounts of borate groups were prepared by chemical immobilization ofP-aminoethylphenylboric acid on a copolymer- treated organosilane spacer glass plates. It was found thatbaker's yeast cells selectively adhered to these supports. Yeast cells stained with procion red HE-3B formeddenser and more stable layer on the copolymer-grafted supports compared onto ...
متن کاملBorane-functionalized silica supports In situ activated heterogeneous zirconocene catalysts for MAO-free ethylene polymerization
We treated silica with tris(pentafluorophenyl)borane, B(C6F5)3, to create borane-functionalized support, SiO2–B(C6F5)3 which was then used as a support and co-catalyst for the in situ activated dichloro-zirconocene (Cp2ZrCl2/TIBA) and dimethyl-zirconocene catalyst systems (Cp2Zr(CH3)2) for ethylene polymerization. The surface modifications of SiO2– B(C6F5)3 was investigated by SEM–EDX, FTIR and...
متن کاملPolysiloxanes as supports for catalysts
Introduction Immobilization (heterogenization) of catalysts aims to obtain catalysts which combine the advantages of homogeneous catalysts (high activity, selectivity) and heterogeneous ones (stability, ease of separation from the reaction medium and the possibility of re-use in subsequent reaction cycles). One of the most promising directions of research in this field is the use of polymers as...
