Sulfurization of 1,3-diarylpropanetrione (<B>1</B>) with hydrogen sulfide and hydrogen chloride afforded a mixture of 4-hydroxy-3,5-diaryl-1,2-dithiolium chlorides (<B>3</B>) and 3,5-diaryl-1,2-dithiolium chlorides (<B>4</B>). Treatment of a mixture of <B>3a</B> and <B>4a</B> with triethylamine in alcohol gave anhydro-4-hydroxy-3,5-diphenyl-1,2-dithiolium hydroxide (<B>5a</B>) and the 4-substituted product (<B>6</B>). Sulfurization of dibenzoyldibromomethane yielded 3,5-diphenyl-1,2-dithiolium bromide. Reactions of 5a with picric acid and acetic anhydride in the presence of perchloric acid were carried out.
