Abstract
The pyrolysis of dimethyl and diethyl disulphides and ''disulphide oil '' (a waste product of oil refining) was carried out at 580-610 degree s C. On the basis of the gas-phase reaction of ''disulphide oil'' with the chlorobenzene-acetylene system or 2-chlorothiophene-acetylene sys tem, new methods have been developed for the simultaneous production o f thiophene and benzothiophene or thiophene and thienothiophene in hig h yields. The mechanism of the reactions studied are discussed.
