Abstract
The reaction of bis (trifluoromethyl)ketene with bis(trifluoromethyl)methionic anhydride at 200°C has given hexafluorothioacetone dioxide trimer; 2,2,3,3-tetrakis (trifluoromethyl)thiirane 1,1-dioxide is formed as a byproduct. The same trimer is obtained by heating hexafluoroisobutenylidene sulfate and by treating hexafluoro-αH-isobutyric acid with sulfur trioxide.
