precursors were prepared by oxidative polymerization 3-phenyl-3,4-dihydro-2H-benzo[e][1,3] oxazine (P-a) alone and in the presence of thiophene (Th) with ceric ammonium nitrate in acetonitrile. The structure of the precursors was confirmed by FTIR, H-1 NMR, and DSC measurements, indicating the presence of a cyclic benzoxazine structure, together with small but varying amount of a ring opened phenolic structure. The resulting polymers exhibit conductivities around 10(-2) S cm(-1) and undergo thermal curing at various temperatures. Attempts to copolymerize P-a with another electroactive monomer, pyrrole (Py), by a similar redox process were unsuccessful, which was attributed to the unfavourable oxidation potential of Py. The cured products exhibited high thermal stability but lower conductivity, than those of the precursors. (c) 2006 Wiley Periodicals, Inc.

Polymerization and dipole moment of poly(allyl cyanide) Küçükyavuz, Zühal; Usanmaz, Ali; Testereci, Şenay (Elsevier BV, 1990-9) Polymerization of allyl cyanide was carried out by radiation and chemical catalysis. Polymers obtained by γ-rays under various conditions such as in bulk and in the presence of either air or 0.1 mol% ZnCl2 were oily or solid dark-brown products with molecular weights up to 1.4 × 104. The polymers obtained by n-BuLi was a pale-yellow solid, insoluble in common organic solvents and water. No polymer was obtained with BF3O(C2H5)2. The mechanism of polymerization was shown by infra-red investigation to be diffe...
Synthesis of 1,2,3,5- tetrasubstituted pyrrole derivatives via 5-exo-dig type cyclization and stereoselective functionalisation of ferrocene derivatives Kayalar, Metin; Demir, Ayhan Sıtkı; Department of Chemistry (2005) A convenient and new method for the synthesis of 1,2,3,5-tetrasubstituted pyrrole derivatives starting from 1,3,-dicarbonyl compounds through acid catalyzed cyclization reaction is described. Alkylation of 1,3-dicarbonyl compound with propargyl bromide followed by one step cyclization with the introduction of primary amines in the presence of catalytic amount of triflouroacetic acid (TFA) affords the corresponding pyrrole derivatives in high yields. The investigations on the studies of developing a new meth...
Synthesis of ferrocenyl pyrazoles by the reaction of 3-ferrocenylpropynal with hydrazinium salts Zora, Metin; Odabasoglu, Mustafa; Bueyuekguengoer, Orhan; Turgut, Guenseli (Elsevier BV, 2008-01-01) Synthesis of ferrocenyl-substituted pyrazoles via the reaction between 3-ferrocenylpropynal and hydrazinium salts is described. Depending upon the substitution pattern of hydrazine derivative, the reaction affords 1-alkyl/aryl-5-ferrocenylpyrazoles and/or 1-alkyl/aryl-3-ferrocenylpyrazoles. Structures of 5-ferrocenyl-1-phenyl-1H-pyrazole, 1-benzyl-5-ferrocenyl-1H-pyrazole and 2-(3-ferrocenylpyrazol-1-yl)ethanol were identified by X-ray crystallography.
Synthesis of ferrocenyl quinolines Zora, Metin (Elsevier BV, 2008-06-01) A convenient one-pot synthesis of ferrocenyl-substituted quinolines via a molecular iodine-catalyzed reaction of ferrocenylimines with enolizable aldehydes is reported. First, nucleophilic addition of the in situ generated enol to ferrocenylimine produces beta-anilinopropionaldehyde, which then undergoes intramolecular Friedel-Crafts reaction to give dihydroquinoline derivative. Finally, subsequent dehydration and aerobic oxidation affords ferrocenyl quinolines.
Synthesis and optical properties of light-emitting π-conjugated polymers containing biphenyl and dithienosilole LIAO, Liang; Çırpan, Ali; CHU, Qinghui; KARASZ, Frank E.; PANG, YI (Wiley, 2007-05-15) Copolymers containing oligo(phenylene vinylene) (2.5), fluorene, and 4,4-dihexyldithienosilole (DTS) units were synthesized and characterized. The pi-conjugated monomers were joined with the palladium(0)-catalyzed Suzuki-Miyaura coupling reaction, thus forming either biphenyl- or phenyl-thiophene linkages. These polymers were photoluminescent, with the fluorescent quantum efficiency between 54 and 63% and with),lambda(max) for fluorescence at similar to 448 nm in tetrahydrofuran. The presence of 5% DTS in t...
