Redox chemistry of thiophene, pyrrole and thiophene-pyrrole-thiophene oligomers

Synthetic Metals, 1999
Abstract Electrochemical properties of oligopyrroles and thiophene-pyrrole-thiophene oligomers, which are key-step intermediates in electropolymerization processes, have been investigated by means of fast electrochemistry, flash photolysis and pulse radiolysis techniques.

Double photoionization of thiophene and bromine-substituted thiophenes

The Journal of Chemical Physics, 2008
We report the double photoionization spectra of thiophene, 3-bromothiophene, and 3,4-dibromothiophene using a coincidence spectroscopy technique based on electron time-of-flight measurements. Spectra have been recorded between the onset and 40.814 eV using He IIα radiation. The He I photoelectron spectrum of 3,4-dibromothiophene has also been measured.

Electrophilic phenylselenenylation of thiophenes. Synthesis of poly(phenylseleno)thiophenes.

Tetrahedron, 1994
Abstract The phenylselenenyl sulfate, generated from the oxidation of diphenyl diselenide with ammonium persulfate, easily effects electrophilic aromatic substitution reactions on thiophene, 2- and 3-methylthiophenes and on 3-bromothiophene. The phenylseleno group activates the substrate to further substitution.

Electrophilic substitution on the thiophen ring. Part I. Bromination of thiophen and deuteriated thiophen

Journal of the Chemical Society B: Physical Organic, 1970
A study of salt effects and activation parameters indicates that the mechanism of bromination of thiophen in aqueous acetic acid is the same as that of benzene compounds. There is an isotope effect (kH/kD) of 1·3, which is shown to be secondary and does not represent slow proton loss.

Thiophene

2000
Abstract Thiophene can be found in peat, coal tar and gas, and technical grades of benzene. It has similar physical properties to benzene and may be used as a solvent. Thiophene is used to manufacture resins with phenol and formaldehyde, dyes, and pharmaceuticals, including dopamine-uptake antagonists and anticonvulsants.

Electronic spectrum of thiophen and some deuterated thiophens

Journal of the Chemical Society, Faraday Transactions 2, 1972
The electronic absorption spectra of thiophen and of some deuterated thiophens have been studied in the range 2500–1400 A. Three electronic transitions, with origins at 41 595, 48 330 and 53 270 cm–1 in C4H4S and two Rydberg series leading to the limit 71 570 cm–1 were analyzed.

9.10.4 Thiophenes, Thiophene 1,1-Dioxides, and Thiophene 1-Oxides (Update 2011)

2011
Abstract This manuscript is an update to the earlier Science of Synthesis contribution describing methods for the synthesis of thiophenes. The main focus lies on modern synthetic transformations, such as transition-metal-mediated coupling reactions, leading to functionalized thiophenes.
