Polarographic half-wave potentials for two reduction steps of 49 cyclopentadienyliron complexes of substituted arenes or heterocycles in dimethylformamide were determined. A fast cyclic voltammetry (10–40 V/s) was used to study the electron transfer kinetics of some of these complexes. After corre...

Electrochemical reduction studies of a series of η6-polycyclic and η6-heterocyclie arene-η5-cyclopentadienyliron cations were carried out in different solvents and at different temperatures. The complexes were reduced in two one-electron steps. Stability of the first reduction product was much hi...

Radical polymerization of organoiron (alkynyl methacrylate)s afforded a series of organoiron poly(alkynyl methacrylate)s with the ability to coordinate dicobalt hexacarbonyl. The polymers were post-modified with dicobalt hexacarbonyl moieties through reaction with dicobaltoctacarbonyl. Gel permeatio...

Recent development in the field of organometallic and coordination polymers based on transition metals, particularly the methods and degree of polymerization, the nature of bonding present, and the type of metal moiety, has become an area of ever-growing interest. Metal-containing polymers have cata...

Metal-containing conducting polymers are a new and interesting class of materials that combine some of the redox properties of conducting polymers and some of those of the metal ions. In metal-containing conjugated polymers, there are several possible arrangements of metal group relative to the back...

Esterification reaction of organoiron complex with terminal carboxylic group with hydroxymethyl EDOT(3,4-ethylenedioxythiophene) and 2-(3-Thienyl) ethanol produced EDOT and thiophene monomers. The electrochemical polymerization of these monomers led to new polymeric materials with the conjugated sys...

A unique route to the synthesis of 2-alkyl-2-arylphenylsulphonylacetonitriles via the nucleophilic aromatic substitution (SNAr) of chloroarene cyclopentadienyliron complexes with 2-alkyl phenylsulphonylacetonitriles has been investigated. Reactions of chloroarene complexes (1a–d) with 2-alkyl phen...

Non-isothermal crystallisation studies of Organoiron poly(alkynyl methacrylate)s coordinated to dicobalt hexacarbonyl using differential scanning calorimetry (DSC) are reported. Two exothermic peaks appear on crystallisation of the polymers under investigation. Four isoconversional methods (the diff...

Organoiron polymers with azo dyes pendant to the backbone incurred loss of color upon irradiation with UV light (λ = 300 nm) in acetonitrile solution. The loss of color is attributed to the interaction of the cleaved iron moiety with the azo chromophore. Similarly, addition of small amounts (⩽1 m...

Polarog. half-wave potentials for 2 redn. steps of 49 cyclopentadienyliron complexes of substituted arenes or heterocycles in DMF were detd. A fast cyclic voltammetry (10-40 V/s) was used to study the electron transfer kinetics of some of these complexes. After correction for the double layer effect...

Over the past few decades, there has been tremendous interest in the chemistry of arenes coordinated to transition metal moieties due to their applications in the fields of organic and polymer synthesis. The electrophilicity of coordinated arenes allows for reactions with a number of carbon-, oxygen...

Novel polynorbornenes containing cationic cyclopentadienyliron moieties pendent to the polymer side chains were prepared via polymerization of metallated norbornene monomers using Grubbs' catalyst. Thermogravimetric analysis of the organometallic polymers showed two weight loss steps: the first at 2...
