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 was tremendous interest in the chem. of arenes coordinated to transition metal moieties due to their applications in the fields of org. and polymer synthesis. The electrophilicity of coordinated arenes allows for reactions with a no. of C-, O-, N- and S-contg. nucleo...

Nucleophilic substitution reactions with the cyclopentadienyliron (CpFe) complex of m- or p-Cl2C6H4 with carbanion nucleophiles derived from Et acetoacetate (EAA), dibenzoylmethane (DBM) or diacetylmethane gave only monosubstitution as previously obsd. for the CpFe complex of o-Cl2C6H4. Reaction of ...

The electrochem. behavior of cyclcopentadienyliron contg. complexes and polymers has given rise to useful materials, such as electrochem. probes for biol. systems, electrocatalysts, and electrochem. switches.The development of new systems contg. cyclopentadienyliron complexes can only improve and in...

Polynorbornenes contg. cationic cyclopentadienyliron moieties were prepd. via ring-opening metathetic polymn. of metalated norbornene monomers in the presence of a Ru-based catalyst. The resulting organometallic polymers were characterized using spectroscopic, electrochem., and thermal techniques. [...

A review presents all classes of macromols. contg. iron-carbon bonds and highlights some examples of these materials. Ferrocene-based polymer, polymers contg. cyclopentadienyliron complexed arenes or iron carbonyl complexes, iron polyynes, and polymer with Fe-Fe bond are discussed. The methods utili...

A review. A no. of synthetic routes was utilized in the prodn. of organometallic monomers and polymers contg. arenes coordinated to the Group VI, VII and VIII transition metals. Transition metal-coordinated monomers were prepd. either by nucleophilic arom. substitution reactions of transition metal-...

A review, with ∼9 refs., of the use of NMR spectroscopy for the detn. of the structure of a no. of cyclopentadienyliron arene systems. The examples presented here demonstrate the use of 1- and 2-dimensional NMR techniques in predicting the chem. structure and dynamics of these complexes. The nu...

A review. This article provides a comprehensive review of the synthesis, properties and applications of organometallic polymers of the transition metals. The different classes of organometallic polymers are described according to their structural make-up, as well as by their methods of synthesis. A ...

A series of cyclopentadienyl-iron-complexed azo-functionalized polymers were synthesized. The visible spectra of the azo dyes changed upon reaction with organometallic complexes; however, the absorption spectra of the monomers and polymers were similar. Photolysis of the organoiron polymers allowed ...

Hydride and cyanide addn. to di- and polycyclopentadienyliron arene complex cations with etheric bridges is described. Reaction of the di-Fe complexes with NaBH4 gave a no. of adducts. P-Methyl- and o,o-dimethylphenoxybenzene cyclopentadienyliron complexes were used as models in this study to allow ...

Arylated phenylsulfonylacetonitriles, e.g., PhCH(CN)SO2Ph, and Et cyanoacetates, e.g., PhCH(CN)CO2Et, were prepd. by nucleophilic substitution of cyclopentadienyliron complexes of chloroarenes, e.g., I, with NCCH2R (R = SO2Ph, CO2Et) in the presence of potassium carbonate in DMF followed by photolys...

The reaction of aliph. primary amines with phenolphthalein-contg. dicyclopentadienyliron complexes led to etheric bond cleavage. This unique cleavage reaction is due to nucleophilic attack by the amines ipso to the etheric group of the complexed arene, which is activated by coordination to the catio...

As functionalization of the polynorbornene backbone has shown to be a viable route towards altering the thermal and chem. properties of the resulting polymeric material, our focus was on the prepn. of norbornene monomers contg. a side-chain consisting of a rigid mesogen and/or an aliph. spacer.
