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...

The reaction of dimethyltin dichloride with 1,5-bis(2′-pyridyl)pentane-1,3,5-trione (Htrione) resulted in the formation of the dinuclear complex {[Me2ClSn(μ-trione)SnMe2Cl2]·Htrione} (1) in the solid state. The solid state X-ray determination of the complex {[Me2ClSn(μ-trione)SnMe2Cl2]·Htrione...

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...

Cyclic aryl ethers, thioethers or amines, and methods for synthesis are
disclosed. These cyclic aryl compounds are synthesized by combining a first
dinucleophile with a substituted benzene metallized electron-withdrawing
complex,
having halo or nitro substituent groups, to form a li...

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...

Nucleophilic substitution reactions with the cyclopentadienyliron (CpFe) complex of m- or p-dichlorobenzene with carbanion nucleophiles derived from ethyl acetoacetate (EAA), dibenzoylmethane (DBM) or diacetylmethane (DAM) were found to give only monosubstitution as previously observed for the CpFe ...

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...

Sol. organoiron polyethers, thioethers, and amines were synthesized via nucleophilic arom. substitution reactions. The synthesis of these classes of organometallic polymers involved either the reaction of cyclopentadienyliron complexes of dichloroarenes with various oxygen and sulfur dinucleophiles ...

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...
