Ferraris, John P. published the artcileGrafting of buckminsterfullerene onto polythiophene: novel intramolecular donor-acceptor polymers, Application of Thiophen-3-ol, the publication is Optical Materials (Amsterdam) (1998), 9(1-4), 34-42, database is CAplus.

Conjugated polymer-fullerene composites have shown efficient photoinduced charge transfer. The attachment of a fullerene moiety to the conducting polymer backbone is expected to lead to materials with more intimate association of the donor/acceptor sites. Two approaches to the attachment of fullerenes onto polythiophene derivatives were explored. In the first case, C₆₀ fullerene was bonded to a bithiophene derivative which can be electropolymerized In the second, solvent-processable polythiophene copolymers were prepared and functionalized with fullerene. Both these systems exhibit electrochem. and optoelectrochem. properties for fullerene and the conducting polymer, as seen in cyclic voltammograms and UV-visible spectra.

Wentworth, Anita D. published the artcileA Soluble Polymer-Supported Triflating Reagent: A High-Throughput Synthetic Approach to Aryl and Enol Triflates, Formula: C4H4OS, the publication is Organic Letters (2000), 2(4), 477-480, database is CAplus and MEDLINE.

The high-yielding synthesis and application of the first example of a polymer-supported reagent for the preparation of trifluoromethanesulfonates (triflates), 4-(F₃CSO₂)₂NC₆H₄(OCH₂CH₂)_nOC₆H₄N(SO₂CF₃)₂, is described. This new reagent efficiently triflates aryl alcs. and lithium enolates in high yield (>90%). A simple precipitation and filtration to remove the excess reagent and byproduct facilitate purification of the triflate products. The PEG-supported approach is highly efficient, as the PEG-supported byproduct can be quant. recovered and recycled into reagent.

Iranpoor, Nasser published the artcileNickel-Catalyzed One-Pot Deoxygenation and Reductive Homocoupling of Phenols via C-O Activation Using TCT Reagent, Safety of Thiophen-3-ol, the publication is Organic Letters (2015), 17(2), 214-217, database is CAplus and MEDLINE.

A new method for C-O bond activation of phenolic compounds has been achieved using 2,4,6-trichloro-1,3,5-triazine (TCT) to utilize in one-pot Ni-catalyzed deoxygenation and reductive homocoupling reactions. With this simple method, phenolic compounds were converted to their corresponding arenes or biaryl compounds under mild conditions [e.g., treatment of 2-naphthol with TCT followed by NiCl₂(PCy₃)₂ and MeOH/Zn/KI afforded naphthalene (85%), and treatment of p-cresol with TCT followed by NiCl₂(PCy₃)₂ and Zn/Et₄NI afforded 4,4′-dimethylbiphenyl (84%)]. The introduced methodol. has a broad scope and demonstrates good functional group compatibility.

A novel, and efficient nickel-catalyzed deoxycyanation of phenolic compounds using relatively nontoxic Zn(CN)₂ as the cyanide source was developed. The reaction of C-O bond activated phenolic compounds by 2,4,6-trichloro-1,3,5-triazine with Zn(CN)₂ in the presence of a nickel precatalyst afforded the aromatic nitriles in good to excellent yields.

Electronic effects of substituents, Application In Synthesis of 17236-59-8, the publication is Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya (1983), 828-35, database is CAplus.

The activity and selectivity of the electrophilic reactions of monosubstituted benzenes, thiophenes, furans, and pyrrole were studied by calculating localization energies by the CNDO/2 MO method. Anal. of theor. and exptl. reactivity indexes indicated a difference in the transfer of substituent effects from the α and β positions of the 5-membered heterocycles. Orbital interactions must be calculated to explain the selectivity of electrophilic reactions of the 5-membered heterocycles.

Efficient synthesis of benzodithienofurans (BDTF) e.g. I and benzodithienothiophenes (BDTT) e.g. II were achieved by the combination of an addition-elimination reaction, reduction and Pd-catalyzed dehydrogenative cyclization. The synthesis of Π-extended BDTF and BDTT derivatives through the use of coupling reactions was also achieved. The detailed phys. properties like DFT, cyclic voltametry, UV visible absorption and fluorescence of these compounds were investigated. The newly synthesized BDTFs exhibited strong fluorescence compared with BDTTs. 2,2′-bis([1]benzothieno[3,2-b]thieno[2,3-d]furan) (BBTTF) exhibited p-type organic field-effect transistor (OFET) properties.

Mohan, C. Gopi published the artcileElectrostatic potential mapping using hybridization displacement charge: atomic parameters and transferability of charge and potential, Category: alcohols-buliding-blocks, the publication is International Journal of Quantum Chemistry (1998), 66(2), 149-156, database is CAplus.

Mol. electrostatic potential (MEP) maps and MEP-derived charges for certain mols. were studied by the ab initio approach using the 6-31G basis set. These results were used to obtain the parameters (K and ζ) for fluorine, sulfur, and chlorine required for the hybridization displacement charge (HDC) calculations employing the MNDO and AMI methods. The HDC combined with Loewdin charges, distributed continuously in three-dimension spherically and sym., were shown to reproduce ab initio MEP features of mols. fairly well. This method of computing the MEP was applied to two mols. of pharmacol. importance, namely, dimaprit and mustard gas. It is shown by studying the cis and trans forms of two amino acids that transferability of the MEP is appreciably less acceptable than that of charges in going from one conformation to the other.

Hunter, Gordon A. published the artcileSynthesis of 3-hydroxythiophenes and thiophen-3(2H)-ones by pyrolysis of alkylsulfanylmethylene Meldrum’s acid derivatives, Name: Thiophen-3-ol, the publication is Journal of the Chemical Society, Perkin Transactions 1: Organic and Bio-Organic Chemistry (1995), 1209-14, database is CAplus.

3-Hydroxythiophene [thiophen-3(2H)-one] and a range of its 2-substituted, 2,2-disubstituted and 5-substituted derivatives have been made by flash vacuum pyrolysis (FVP) of an appropriate alkylsulfanylmethylene derivatives of Meldrum’s acid. These compounds are readily obtained, either by reaction of methoxymethylene Meldrum’s acid with alkylthiols in refluxing acetonitrile, or via the bis(methylsulfanyl) compound I by known procedures. The pyrolysis proceeds by a hydrogen-transfer-cyclization mechanism in which there is extensive loss of configuration of a chiral center at the reaction site. The NMR and mass spectra of the Meldrum’s acid precursors and the mass spectra of the 3-hydroxythiophenes [thiophen-3(2H)-ones] are briefly discussed.

Hunter, Gordon A. published the artcileChemical and spectroscopic properties of the 3-hydroxythiophene [thiophen-3(2H)-one] system, Name: Thiophen-3-ol, the publication is New Journal of Chemistry (2010), 34(11), 2558-2563, database is CAplus.

3-Hydroxythiophene 1 spontaneously dimerizes to 4,5-dihydro-5-(3-hydroxythien-2-yl)thiophen-3(2H)-one 14. 3-Hydroxythiophenes 1E and 4-10E exist in solvent-dependent equilibrium with their thiophen-3(2H)-one 1K and 4-10K tautomers; the amount of hydroxy tautomer is greater than in the case of the corresponding 3-hydroxypyrroles. 3-Hydroxythiophenes are much less reactive to electrophiles than corresponding 3-hydroxypyrroles, but the 5-methylsulfanyl derivative 10 reacts at the 2-position with methoxymethylene Meldrum’s acid and undergoes Vilsmeier formylation. The enolates derived from 3-hydroxythiophenes by treatment with base can be O-alkylated and O-acylated with high regioselectivity. 2,2-Disubstituted thiophen-3(2H)-ones undergo equilibrium conjugate addition with nucleophiles, but the resulting adducts could not be isolated.
