The mechanism of formation of TTN (an important precursor to tetrathiafulvalene (TTF)) from 4,5bis(benzoylthio)-1,3-dithiole-2-thione is discussed. Contrary to previous reports, ethylenetetrathiolate is not an intermediate in this synthesis, whereas 4,5-vinylenedithio-1,3-dithiole-2-thione is likely
the effect of all, due to the customary greater importance of d,-$, interactions relative to those of the c',-Q1 type. In this event, a metallic species with contracted dT orbitals (i.e., a small metal or one in a high oxidation state) would likely favor top-side bonding (viz., z), whereas one with
