A new method has been developed for the synthesis of 2,3-disubstituted benzothiophenes involving the palladium-catalyzed annulation of arylsulfides 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

tert-butoxide (t-BuOK), the cross-coupling reaction between aryl fluorides and dimethyldisulfide was developed. A series of aryl methyl sulfides were obtained in moderate to good yields undertransition-metal-free and mildconditions.

of chalcogenoether motifs in Pd-catalyzed atroposelective C−Holefination and allylation are presented. The thioether motif was found to be a superior directing group compared to the corresponding ether (−OR) and selenoether in terms of reactivity and enantiocontrol. The selenoether unit (−SeMe) was used for the first time as a suitable directing group in asymmetric C−H activation.
