Abstract
Substituted 1,3-dithiole-2-ones 2 a - f are obtained by reaction of 1,3-dithiole-2-thiones 1 a - f with mercuric acetate. The thiones 3 react with triethyloxoniumtetrafluoroborate giving 1.3-dithiolium salts 4 a - h . The cyclocondensation of compounds 3 to thieno[2,3-d]-1,3-dithiole- 2-thiones 6 a - c is described. The first synthesis of 5-methylthio-2-thioxo-1,3-dithiole- 4-carboxylic acid is reported.
