Utilizing organoiron-mediated nucleophilic arom. substitution, a no. of allylamine-contg. organoiron complexes were prepd. Amide formation between 1,1'-ferrocene dicarbonyl chloride and allylamine produced a similar ferrocene compd. These materials were subjected to hydrosilation with methyldiethoxy...

Irradiation of 2-adamantane-2,3'-[3H]-diazirine (1) in isooctane at room temperature gives two primary photoproducts, 2-diazoadamantane and 2-adamantylidene (Ad:), with quantum yields of about 0.5 each. The fluorescence quantum yield of 1 is small, phi(f) approximate to 10(-4). The reactivity of Ad:...

With nucleophilic arom. substitution and ester condensation reactions, several new first-generation dendrimers and star-shaped mols. contg. cationic cyclopentadienyl iron moieties were prepd. Although the soly. of the organoiron star-shaped mols. with ether bridges in polar solvents was found to dec...

Dimethylplatinum(II) complexes [PtMe2(NN)] {NN = bpy (2,2'-bipyridine), phen (1,10-phenanthroline) or bu2bpy (4,4'-di-tert-butyl-2,2'-bipyridine)} were reacted with alkyl halides (RX = EtI or EtBr, NN = bu2bpy; RX = nBuBr, NN = bpy; RX = CHPh2Br, NN = bpy, phen, or bu2bpy) to yield the Pt(IV) comple...

A review of classes of organoiron polymers contg. azo dyes pendent to, or in their backbone which were prepd. The 1st class includes cationic organometallic polyethers, polythioethers and polynorbornenes incorporating aryl and hetaryl azo dyes. These organometallic polymers were synthesized via nucl...

A new class of macromols. contg. neutral and cationic organoiron moieties with arylazo chromophores in their backbones has been prepd. Photolysis of these polymers resulted in the removal of the cationic iron moieties leading to new polyferrocenes with azo dyes in their backbones. UV-vis studies sho...

A no. of red to violet thienyl-2-azo and thienyl-5-azo disperse dyes were prepd. using Gewald's methodol. Structural characterization of these dyes was carried out using IR, NMR, and mass spectroscopies. UV-visible studies of the dyes in a no. of polar solvents showed a considerable difference in th...

A series of coumarins were reacted with methacrylate or styrene derivs. to form new olefinic coumarin monomers that were polymd. using 2,2'-azobisisobutyronitrile. These polymers were highly insol. in org. solvents and displayed good thermal stability with glass-transition temps. 70-130°. Lumines...

Ferrocene-based polymers contg. azo groups in their backbone were synthesized by condensation polymn. of a cationic organometallic monomer contg. two azo dye moieties and ferrocene in the backbone as well as pendent cationic iron groups with 1,3-diaminopropane, 4,4'-thiobisbenzenethiol or bisphenol ...

Nucleophilic arom. substitution of cyclopentadienyliron complexes of chloroarenes with oxygen-contg. nucleophiles led to the isolation of a no. of arom. ether complexes in very good yields. Reactions of these complexes with 1-naphthol, followed by removal of the cyclopentadienyliron moieties produce...

Poly-norbornene homo- and copolymers contg. aryl- and/or hetaryl-azo dyes were prepd. through ring-opening metathesis polymn. (ROMP). Thermal studies indicated that the polymers were thermally stable up to 250°, and possessed glass transition temps. ranging from 93 to 133°. In THF solns., the ...

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 ...

The through space singlet-singlet and triplet-triplet energy transfers in cofacial bis(etio-porphyrins) rigidly held by the carbazoyl spacer (3,6-bis(tert-butyl)-1,8-bis[5-(2,8,13,17-tetraethyl-3,7,12,18-tetramethylporphyrinyl)]carbazole, H4L), were studied.

A no. of classes of polynorbornenes contg. cationic iron moieties within their side chains were prepd. via ring-opening metathesis polymn. with a ruthenium-based catalyst. The iron-contg. polymers displayed excellent soly. in polar org. solvents. The wt.-av. mol. wts. of these polymeric materials we...
