Flexible Routes to Thiophenes

Organic Letters, 2014
Three convergent routes to thiophenes are described, hinging on the radical addition of α-xanthyl ketones to ethyl vinyl sulfide or to vinyl pivalate. The latter route ultimately proved to be the most versatile and efficient (61-94%)

Thiophenes

, 2014
The chemoselective synthesis of indeno[1,2-b]thiophenes was developed through the annulation of α-enolic dithioesters with ninhydrin under solvent-free conditions.

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.
