Notes:
1,2-Diphenyl-1,2-bis(trimethylsilyl)ethene (5) undergoes a smooth reductive metallation with metallic lithium to yield the corresponding dilithioethane derivative (Li2·5). The structure of this new compound in [D8]THF solution was determined by NMR spectroscopy (1H, 13C, 6Li, 7Li NMR and 6Li,1H-HOESY). It is shown that the phenyl rings have a high quinoid character and that the lithium cations are relatively mobile.
