Palladium-Catalyzed Direct C–H Arylation of 3‑(Methylsulfinyl)thiophenes

A palladium-catalyzed direct arylation of (3-thiophene)­S­(O)­Me derivatives has been developed. This protocol is effective for the selective synthesis of 2-arylated and 2,5-diarylated sulfinylthiophene derivatives with as low as 0.5 mol % catalyst loading. Various functional groups are well tolerat...

Zusammenfassung:A palladium-catalyzed direct arylation of (3-thiophene)­S­(O)­Me derivatives has been developed. This protocol is effective for the selective synthesis of 2-arylated and 2,5-diarylated sulfinylthiophene derivatives with as low as 0.5 mol % catalyst loading. Various functional groups are well tolerated. A method to install two different aryl groups on 3-(methylsulfinyl)­thiophenes is also introduced.
