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...

The ecteinascidins are a family of tetrahydroisoquinoline alkaloids isolated from the tunicate Ecteinascidia turbinata. Ecteinascidin 743 is a candidate for the treatment of several human cancers. Ecteinascidins have been shown to kill tumor cells in vitro, inhibit tumor growth in vivo, suppress all...

Polyethers and/or thioethers contg. organoiron moities in either the backbone or the side chain were prepd. under mild reaction conditions. Polysiloxanes contg. arene cyclopentadienyliron or ferrocene moieties were also prepd. and their morphol. thermal and spectroscopic characterizations were examd...

Ferrocene-based monomers were prepd. via the reaction of cationic chloroarene cyclopentadienyliron complex cations with 1,1'-ferrocene dicarbonyl chloride. These monomers were then reacted with O-, S- and N- contg. dinucleophiles to give the polymeric materials with neutral iron moieties in the back...

Isomeric dichlorobenzene complexes of ironcyclopentadienyl and pentamethylcyclopentadienyl- ruthenium were used to facilitate nucleophilic arom. substitution (SNAr) reactions with a variety of O, S, and N contg. nucleophiles. Oligomeric and polymeric systems were achieved by variation in the ratio o...

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 linear bimetallized...

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. ...

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 substituted arene cyclopentadienyliron complexes were reacted with phenolphthalein in the presence of potassium carbonate using DMF as a solvent to prep. di-iron complexes as shown in the following scheme. Subsequent reaction with n-butylamine resulted in an unprecedented cleavage of the et...

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...

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...

A review. Metallodendrimers can be assembled in a no. of ways (covalent, ionic, hydrogen-bonding, coordination), wherein the metal plays key roles: sensor, catalyst, electronic, magnetic, or optical device. The mol. engineering pertaining to the metallodendritic design is relevant to multiple aspect...
