Abstract:

First row transition metal complexes of phthalocyanine are employed as catalysts for the oxidation of cyclohexene and cyclooctene using iodosylbenzene and pentafluoroiodosyl benzene. The catalysis was performed in dichloromethane: methanol:water (80:18:2) solvent mixture.  The products of the catalysis for cyclohexene are epoxycyclohexane, 2-cyclohexene-1-ol and 2-cyclohexene-1-one whereas for cyclooctene it is specifically cyclooctene oxide.  For cyclohexene oxidation epoxide yield and selectivity is in the order of MnII > FeIII > FeII > CoII > CrIII > NiII > CuII , while for 2-cyclohexene-1-one production the ability of the catalysts are in the order of  NiII > CoII > CuII > CrIII > FeIII > FeII > MnII .

Density Functional Calculations on First-Row Transition Metals

The excitation energies and ionization potentials of the atoms in the first transition series are notoriously difficult to compute accurately. Errors in calculated excitation energies can range from 1–4 eV at the Hartree-Fock level, and errors as high as 1.5eV are encountered for ionization energies. In the current work we present and discuss the results of a systematic study of the first trans...

Selective Oxidation of Cyclohexene, Toluene and Ethyl Benzene Catalyzed by Bis-(L-tyrosinato)copper(II), Immersed in a Magnetite-Infused Silica Matrix

Bis-(L-tyrosinato)copper(II) was reacted with 3-(chloropropyl)-trimethoxysilane functionalized silica that has infused magnetite to yield a magnetically separable catalyst in which the copper carboxylate is covalently linked to the silica matrix through the silane linkage. The immobilized catalyst has been characterized by spectroscopic studies (such as FT-IR, EPR, Magnetic Measurement...

Optimization of reaction conditions and effect of catalyst type on product distribution in Cyclooctene oxidation

Oxidation of cyclooctene was studied in presence aqueous hydrogen peroxide (30%, v/v) over nano iron oxide. The catalyst prepared by microemulsion method and characterized using various techniques including XRD, TEM and BET techniques for evaluating phase, structure and morphology and surface area. In this study, we investigated the effects of varying the catalyst content, reaction temperature,...
