A review. The study of metal-contg. block copolymers represents one of the most active areas in the metallopolymer field. As illustrated in this chapter, exciting possibilities exist for the development of new functional nanostructured materials via simple self-assembly approaches. Despite the obvio...

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...

RCOCH2COR1 (R, R1 = Me, Ph, OEt) are arylated with o-R2C6H4R3Fe+cp PF6- (R2 = H, R3 = Cl, NO2; R2 = R3 = Cl; cp = cyclopentadienyl) in THF-DMSO contg. KF on celite to give 73-80% o-R2C6H4CH(COR)COR1Fe+cp PF6- (same R-R2) in a nucleophilic arom. substitution reaction. [on SciFinder(R)]

Electrolysis of arene and heterocycle cyclopentadienyliron hexafluorophosphates led to the liberation of arenes or heterocycles in 69-90% yield. The procedure described gives yields comparable with or superior to the yields obtained from pyrolytic sublimation used previously. [on SciFinder(R)]

A review covers the recent approaches to metal arrays on artificial DNAs and cyclic peptides. [on SciFinder(R)]

A review. This chapter discusses the synthesis, structures, selected properties, and uses of polymers that have metal-metal bonds incorporated into their backbone chains. These materials are of interest for a no. of reasons. The primary reason is the promise of new and unusual properties. In particu...

A no. of 2-(benzothiazol-2-ylamino)pyrimidines, 2-benzothiazol-2-yl-3-arylacrylonitriles, and benzothiazol-2-ylcoumarins were synthesized by reacting benzothiazole derivs. with dicarbonyl compds. and arom. aldehydes. The unexpected 2-(4-methoxyphenyl)benzo[d]thiazole was obtained as a unique product...

The mol. wt., thermal stability, and cond. of chem. synthesized, self-doped poly(aniline boronic acid) have been detd. Gel permeation chromatog. results indicate a no.-av. mol. wt. of 1,676,000 g mol-1, a wt.-av. mol. wt. of 1,760,000 g mol-1, and a polydispersity of ∼1.05. The high mol. wt. is...

The facile prepn. of macrocyclic ethers, e.g., I (X = direct bond, CMe2), is achieved using SNAr reactions of (dichlorobenzene)CpFe+ complexes with various dinucleophiles, followed by photolytic demetallation; x-ray crystallog. gives unequivocal structural proof for one of these macrocycles.

Polyarom. ethers and thioethers with pendent cyclopentadienyliron moieties have been prepd. in very high yield using a highly efficient and mild methodol. [on SciFinder(R)]

Organoiron polymers with azo dyes pendant to the backbone incurred loss of color upon irradn. with UV light (λ = 300 nm) in acetonitrile soln. The loss of color is attributed to the interaction of the cleaved iron moiety with the azo chromophore. Similarly, addn. of small amts. (≤1 mM) of b...

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...

Our research interests have been focused on the design of new monomeric and polymeric materials using organoiron complexes as precursors. Cyclopentadienyliron chloroarene complexes were used to mediate the synthesis of sulfide contg. compds. These compds. were designed with various arom. and aliph. ...

The synthesis of arom. ether functionalized norbornene monomers was accomplished using chloroarene cyclopentadienyliron complexes. Monomers contg. aliph. ether linkages or bulky arom. ether groups within their structures were synthesized. These monomers were subjected to ring-opening metathesis poly...

Polyarom. ether/imines with pendent cationic cyclopentadienyliron moieties were prepd. using two different synthetic strategies. The first methodol. involved the reaction of diiron complexes contg. terminal complexed chloroarenes with diphenolic compds. In this strategy, the imine functionality was ...

Arom. ether complexes of cyclopentadienyliron contg. pendent carboxylic acid groups were reacted with methacrylate and styrene functionalized mols. These diiron complexes were subsequently polymd. in the presence of AIBN to give the corresponding polymethacrylates and polystyrenes with organoiron fu...

A no. of routes to the synthesis of dendrimeric materials coordinated to the cationic cyclopentadienyliron moiety were explored. As an example, reaction of dichloroarene cyclopentadienyliron complexes with a triphenolic compd. resulted in the formation of a trimetallic ether complex contg. terminal ...

Nucleophilic arom. substitution of p-dichlorobenzene complexed to a cyclopentadienyliron cation with oxygen and sulfur nucleophiles led to the formation of polymers with pendent iron moieties as shown in the following scheme. These polymers were sol. in various org. solvents. Photolytic demetallatio...
