Tetrathiafulvalenes. XXI. Syntheses of Tetrathiafulvalenes from 2-Alkylthio-, 2-Arylthio- and 2-Alkylseleno-1,3-dithiolium SaltsIn the reaction of 2-alkylthio-, 2-arylthio- or 2-alkylseleno-1, 3-dithiolium salts with trivalent phosphorus compounds in acetonitril tetrathiafulvalenes 2 are formed. As an intermediate we suppose a phosphorane, which reacts with further 1,3-dithiolium salt to provide the tetrathiafulvalene. By the application of a 2-alkylthio-1,3-dithiolium salt a monomethin dye is formed in a side reaction. When the reaction is carried out in methanol, the phosphorane is trapped by the solvent and a 2H-1,3-dithiolium salt is obtained.
