Efficient Thiophene Synthesis Mediated by 1,3-Bis(carboxymethyl)imidazolium Chloride: C-C and C-S Bond Formation

Thiophene derivatives have been prepared by means of a functionalized imidazolium salt [1,3-bis(carboxymethyl)imidazolium chloride] acting as a catalyst. The heterogeneous catalyst has allowed to carry out the reactions with no solvent or inert atmosphere

Transition-Metal-Free Sulfuration/Annulation of Alkenes: Economical Access to Thiophenes Enabled by the Cleavage of Multiple C-H Bonds

A novel, atom economical, and transition-metal-free strategy for the synthesis of thiophenes from substituted buta-1-enes with potassium sulfide has been presented. The reaction achieves double C-S bond formations via cleavage of multiple C-H bonds and provides an efficient approach to access various functionalized thiophenes. Moreover, the strategy can also be used for the synthesis of thiophenes from 1,4-diaryl-1,3-dienes. Mechanistically, DMSO plays a role of oxidant and S3?- in situ generated from K2S is involved.

Sulfurative self-condensation of ketones and elemental sulfur: A three-component access to thiophenes catalyzed by aniline acid-base conjugate pairs

A sulfurative self-condensation method for constructing thiophenes 2 by a reaction between ketones 1 and elemental sulfur is reported. This reaction, which is catalyzed by anilines and their salts with strong acids, starts from readily available and inexp

Method for catalyzing terminal alkene and powdered sulfur with copper to react in water phase to generate thiophene ring

The invention discloses a method for catalyzing terminal alkene and powdered sulfur to react in a pure water phase to prepare a thiophene derivative. A water-soluble complex is used as a catalyst, and a one-pot reaction is conducted in the pure water phas

A NOVEL PHOTOREARRANGEMENT OF 2,5-DIARYL-1,4-DITHIIN-1,1-DIOXIDE ACCOMPANIED BY EXTRUSION OF SULFUR DIOXIDE

Photolysis of the title compound afforded 2,5-diarylthiophene.The mechanism involving the valence isomerization to the thioketone was supported by the photolysis in n-butylamine, which gave pyrrole derivatives.

THERMAL AND PHOTOCHEMICAL REARRANGEMENTS OF 1,4-DITHIIN Sulfoxides

Thermolysis of 2,5-diphenyl-1,4-dithiin-1-oxide afforded 2-formyl-2,4-diphenyl-1,3-dithiole, which was obtained also in photolysis along with another rearranged product, 2-benzoyl-4-phenyl-1,3-dithiole.
