Abstract

It is probable that hexafluorothioacetone is formed first and then dimerizes in the presence of excess triphenylphosphine, a known dimerization catalyst. It is rather remarkable that triphenylphosphine removes fluorine instead of sulfur from the di-and polysulfides. This reaction may involve nucleophilic attack of fluorine by phosphorus followed by elimination of a carbanion and decomposition of the carbanion.
