Abstract
The reactions of sulfur with alip-halogen derivatives of 1,2-diphenylethane, 1,2-diphenylethylene, and tetraphenylethane have been studied. A new method for the production of tetraphenylthiophene (from C6H5CHClCHClC6H5), benzothieno[3,2-b]benzothiophene (from C6H5CHClCCl2C6H5), and of 2-phenylbenzo[b] thiophene (from C6H5CHBrCHBrC6H5) has been developed. On being treated with sulfur, tetraphenyl-1,2-dichloroethane is converted into tetraphenylethylene. 1,2-Diphenylethylene reacts with sulfur in the presence of hydrogen bromide forming 2-phenylbenzo[b]thiophene and tetraphenylthiophene.
