A detailed 1H NMR study of the title compds. I (R = Me, R1 = H; R = H, R1 = Cl) using difference NOE spectra and 2-D (COSY) techniques has shown that there is an enhanced restricted rotation about the arene-methine carbon bond with the formation of the complexes. [on SciFinder(R)]

Over the past few decades, we have seen a growing interest in the development of various classes of metal-contg. polymers. While polymers are traditionally carbon-based materials that contain only a few other elements, organometallic polymers could incorporate almost all the other elements of the pe...

A review on the prepn. and uses of organometallic polymers having metal-carbon bonds in the main or side chains or heteroatom-metal bonds in the main chain.

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...

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...

Ring-opening metathesis polymn. of organoiron norbornene monomers functionalized with azobenzene chromophores using the Grubbs catalyst was carried out to prep. the corresponding cationic organoiron polynorbornenes. The chiral monomers were prepd. by coupling reactions of complexes and 5-norbornene-...

The synthesis and characterization of a new class of bis(cyclopentadienyliron) arene complexes of disulfides and diamines with aliph. and arom. bridges are presented. Reactions of the arom. or aliph. dithiols with a wide range of cyclopentadienyliron complexes of chloroarenes (1a-i; shown as I; X = ...

An efficient synthesis of 3-mono or 3,4-disubstituted cinnolines from (o-dichlorobenzene)(cyclopentadienyl)iron hexafluorophosphate in 3 or 4 steps is reported. o-Chlorophenylalkyl or alkylaryl ketone complexes obtained from the o-dichlorobenzene complex upon treatment with enolate anions, react wit...

A novel route to the synthesis of some 2-arylalkanoic acid esters has been achieved. Arom. nucleophilic substitution of various arenecyclopentadienyliron complexes, e.g., I (R = Cl, R1 = H, 3-, 4-Me) with Et ethylacetoacetate and Et methylacetoacetate produced the alkanoic acid ester complexes I (R ...

Arom. nucleophilic substitution reactions (SNAr) of chloroarene cyclopentadienyliron complex cations with K salts of dihydroxyalkanes in a THF/DMF mixt. gave bis(cyclopentadienyliron) arene dications with aliph. ether linkages. Diols were used to produce the diiron complexes I (R = H, x = 2, 4, 6, 8...

Nucleophilic substitution of Cl in the cyclopentadienyliron hexafluorophosphates of chlorobenzene, isomeric chlorotoluenes and dichlorobenzenes I (Cp = cyclopentadienyl, R1 = o-, p-Me, -Cl, m-Cl) with the anions generated from di-Et alkylmalonates R2CH(CO2Et)2 (R2 = Me, Et) leads to the formation of...

Complexes I (R1 = H, Me; R2 = Me, Cl) were used in the prepn. of phenylmalonate esters II. The arylation of CH2(CO2Et)2 by I and K2CO3 gave [(cyclopentadienyliron)phenyl]malonates III, and III underwent pyrolytic sublimation to give II. [on SciFinder(R)]

Recently, we have focused on the synthesis of monomeric and polymeric cationic organoiron functionalized with azo dyes. In this presentation we will describe the synthesis of novel polyferrocene incorporating azo dyes and pendent cyclopentadienyliron cations. Condensation of 1,1'-ferrocenedicar...

A series of coumarins were reacted with methacrylate or styrene derivs. to form new olefinic coumarin monomers that were polymd. using 2,2'-azobisisobutyronitrile.
