Abstract

On the basis of the reaction of sulfur with exo-halogen derivatives of ethylbenzene and styrene, new and simple methods of synthesis have been developed for 2,4-diphenylthiophene (from C6H5CHBrCH3), 2, 5-diphenylthiophene (from C6H5CCl=CH2), 2,3-dichlorothionaphthene (from C6H5CCl2CHCl2), and the previously unknown dithianaphtheno-[2,3-b;2′,3′-e]-1,4-dithiadiene (from C6H5CHClCHClBr). The latter compound is also formed by the action of sulfur on C6H5CCl2CH2Cl or C6H5CHClCHCl2 in the presence of HBr. The derivatives of thianaphthene obtained have been oxidized to the corresponding sulfones.
