Styrene Oxidation by Copper(II) Complexes Salen-Type Encapsulated into Nay Zeolite

Topological Redox Isomers: Surface Chemistry of Zeolite-Encapsulated Co(salen) and [Fe(bpy)3] Complexes

The electroactivity of zeolite-encapsulated redox-active transition metal complexes, {M(L)}Z, was explored for Co(salen) and [Fe(bpy)3] formed in NaY zeolite (where salen ) N,N′-bis(salicylidene)ethylenediamine and bpy ) 2,2′-bipyridine). The zeolite boundary was characterized via X-ray photoelectron spectroscopy (XPS) and cyclic voltammetry in nonaqueous electrolyte at either zeolite-modified ...

Oxidation Chemistry of Metal(II) Salen-Type Complexes

Oxidation of Isoeugenol by Salen Complexes with Bulky Substituents

The catalytic properties of bulky water-soluble salen complexes in the oxidation of isoeugenol (2-methoxy-4-(1-propenyl) phenol) have been investigated in aqueous ethanol solutions in order to obtain a mixture of polymeric compounds through dehydrogenative polymerization. The average molecular weight of dehydrogenated polymers (DHPs) was monitored by GPC and correlated to reaction conditions su...

Dynamics of Water in Zeolite NaY(Br) Investigated by NMR

1. Introduction Zeolites are widely used in industry as molecular sieves, selective adsorbents, catalysts and ion exchangers (e.g. [1] and references therein). Therefore there is a great interest in studying the dynamics of guest molecules in such systems. Although vigorous research has been performed in the field, a complete understanding of the complex behaviour of guest molecules is still mi...

Zeolite Encapsulated Metal Complexes and Their Catalytic Activities: An Overview

The heterogenization of homogeneous catalysts can be achieved by immobilization, grafting, anchoring or encapsulating them in an inert solid like organic polymer or inorganic support. Transition metal complexes having good catalytic properties are immobilized through encapsulation in the super cages of zeolites is called zeolite encapsulated metal complexes (ZEMC) or ship-in-the-bottle complexe...
