Construction of Fused Thiophene Ring System via Intramolecular CH Arylation by Palladium Catalysis
摘要:
Intramolecular CH arylation of a thiophene derivative in the presence of a palladium catalyst furnishes fused tricyclic thiophene in a high yield. The obtained thiophene undergoes further intermolecular CH arylation with a palladium catalyst and AgNO3/KF.
