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.
