Palladium-catalyzed selective 2,3-diarylation of α,α- disubstituted 3-thiophenemethanols via cleavage of C-H and C-C bonds

α,α-Disubstituted 3-thiophenemethanols undergo selective diarylation accompanied by cleavage of the C-H and C-C bonds of the 2- and 3-positions, respectively, upon treatment with aryl bromides in the presence of a palladium catalyst to give the correspond

Palladium-Catalyzed Synthesis of 2,3-Disubstituted Benzothiophenes via the Annulation of Aryl Sulfides with Alkynes

A new method has been developed for the synthesis of 2,3-disubstituted benzothiophenes involving the palladium-catalyzed annulation of aryl sulfides with alkynes. This convergent approach exhibited good functional group tolerance, providing rapid access to a diverse array of derivatives from simple, readily available starting materials. This protocol can also be used to synthesize 2-silyl-substituted benzothiophenes, which can be used as versatile platforms for the synthesis of 2,3-unsymmetrically substituted benzothiophenes.

SYNTHESIS AND REARRANGEMENT OF DIARYL-HYDROXY-BENZOTHIOPHENS. A NEW SYNTHESIS OF 2,3-DIARYL-BENZOTHIOPHENS

The synthesis of some 2-hydroxy-2(H)-3,3-diaryl- and 3-hydroxy-3(H)-2,2-diaryl-benzothiophens (4) and (7) respectively is described; by acidic treatment these compounds readily rearrange to 2,3-diaryl-benzothiophens (5) in almost quantitative yields
