Arylation of Thiocarbonyl Compounds by Arenediazonium Salts

Tetrathiafulvalenes. XXI. Syntheses of Tetrathiafulvalenes from 2‐Alkylthio‐, 2‐Arylthio‐ and 2‐Alkylseleno‐1,3‐dithiolium Salts In 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.
