Abstract: Dithiotropolone (15) has been prepared in ca. 30% yield from tropolone cia the reaction of hydrosulfide ion with 1, 2-diethoxytropylium tetrafluoroborate (13) and isolated as deep red, air-sensitive crystals. Infrared, electronic, and mass spectral characterization data are reported. The tropylium species 13 has been shown to be a potentially valuable intermediate in the synthesis of 1, 7-disubstituted 1, 3, 5-~ ycloheptatrienes. Reactions ...
