The photochemistry of thiophene S-oxides [PDF]
Photochemical & Photobiological Sciences, 2005 Thiophene S-oxides have been prepared and their photoreactivity has been studied. In many cases, the sulfur moiety of the thiophene S-oxides is deoxygenated. Here, the corresponding thiophenes or hydroxylated thiophenes are isolated. In the case of the photoirradiation of tert-butyl substituted thiophene S-oxides, the oxygen of the sulfoxy unit is ...

Journal of Molecular Spectroscopy, 1961
Abstract The microwave spectra of 2- C 13 -thiophene and of 3- C 13 -thiophene have been recorded and analyzed. In addition, three lines from the S 34 -thiophene were found and identified. Taken together with earlier published data for thiophene, thiophene-2 d , and thiophene-3 d , an unambiguous calculation of the (‘ r 8 ’-) structure of ...

Journal of the Chemical Society, Perkin Transactions 2, 1975
LCGO Calculations are reported for the title compounds. A not-planar structure similar to that recently reported for 1-benzylphosphole is more stable than the planar form for the S-oxide. The electron distributions are interpreted in teRms of localised orbitals, and it is clear that the 3d orbitals play a significant part in the bonding of the S-oxide ...

Kinetics of the desulfurization of thiophene: Reactions of thiophene and butene
Journal of Catalysis, 1977Abstract The kinetics of the desulfurization of thiophene on a representative CoOMoO 3 Al 2 O 3 were studied in the temperature range of 250–313 °C for partial pressures of thiophene from 20 to 160 Torr and for partial pressures of hydrogen from 550–750 Torr.

The Versatile Thiophene: An Overview of Recent Research on Thiophene‐Based Materials
Advanced Materials, 2005AbstractIn the last few years, thiophene‐based materials, which are semiconductor and fluorescent compounds, have become a highly interdisciplinary field of research, with diverse studies ranging from the fabrication of electronic and optoelectronic devices to the selective detection of biopolymers.

Bis(ferrocenylsilyl)thiophenes and ferrocenylene(silylene)thiophene oligomers
Polyhedron, 2000Abstract The reaction between 1,1′-dilithioferrocene and 2,5-bis(chlorodimethylsilyl)thiophene ( I ), leads to a series of cyclic oligomers of basic formulation [Fc-SiMe 2 -TH-SiMe 2 ] n ( II ); Fc=(η 5 -C 5 H 4 ) 2 Fe, TH=C 4 H 2 S. The material n =2, IIa , has been completely characterized by spectroscopic and single crystal X-ray diffraction.
