✦ Synopsis


Diphenyl-1,2-bis(trimethylsilyl)ethene (5) undergoes a determined by NMR spectroscopy ( 1 H, 13 C, 6 Li, 7 Li NMR and 6 Li, 1 H-HOESY). It is shown that the phenyl rings have a high smooth reductive metallation with metallic lithium to yield the corresponding dilithioethane derivative (Li 2 •5). The quinoid character and that the lithium cations are relatively mobile. structure of this new compound in [D 8 ]THF solution was
