B(C6F5)3-Catalyzed Hydrodesulfurization Using Hydrosilanes - Metal-Free Reduction of Sulfides

B(C6F5)3-catalyzed hydrodesulfurization of carbon-sulfur bonds was achieved using triethylsilane as the reducing agent. The corresponding products were obtained in good yields under mild reaction conditions. This protocol could be applied to the reduction of sulfides, including benzyl and alkyl sulfides and dithianes, with high chemoselectivities. (Chemical Equation Presented).

Synthesis of unsymmetrical 2,3-diaryl- and 2,4-diarylthiophenes starting from 2,5-dichlorothiophene

Unsymmetrically substituted 2,4-diaryl- and 2,3-diarylthiophenes were synthesized from 2,5-dichlorothiophene via 4-aryl-2-chlorothiophenes in two and four steps including Ni-mediated cross-coupling, respectively. Aluminum chloride-catalyzed reaction of 3-aryl-2-chlorothiophenes with some aromatic ethers unexpectedly led to the formation of the corresponding 2,4-isomers.

A High Yielding Synthesis of 3-Arylthiophenes Under Phase-Tranfer Conditions

A convenient, high-yield method for the large-scale preparation of 3-arylthiophenes by phase-transfer catalyzed (PTC) cyclization of disodium 2-arylsuccinates in o-dichlorobenzene using a mixture of diphosphorus pentasulfide and red phosphorous is described.
