tetrafluorocobaltate(III) to give product mixtures which are similar and which consist mainly of polyfluoro-thiolans and -3-thiolens. One of the major products, 3H/4H-hexafluorothiolan, can be used to prepare tetrafluorothiophen. Manganic trifluoride behaves like potassium tetrafluorocobaltate(III) with thiophen. The mechanisms of these fluorinations are discussed and it is suggested that tetrahydrothiophen is converted

New fluorinatedcyclicsulphides and disulphides have been prepared by the vacuum pyrolysis of tetrafluoroethylene–thiocarbonyl fluoride and tetrafluoroethylene–tetrafluorothiiran copolymers.
