2-Chlorothiophene (1) was found to easily react with certain active aromatic compounds (2) in the presence of AlCl3 under mild conditions, yielding the corresponding 2-arylthiophenes (3) and 5-chloro-2,2′-bithienyl (5) as the main products. With compounds more reactive than 1, the formation of 3 predominated. Reactions of 1 with aryl alkyl ethers, for example, afforded the corresponding 3 in 44–83%
