1,2,3,5-Tetrakis(trifluoromethyl)benzene reacts with phenyl-lithium or t-butyl-lithium to give mixtures of de-aromatised products, derivatives of 2,5- and 2,4-cyclohexadiene-1-ylidene of molecular composition C10H2F10Ph2, C10H2F9Ph3, C10H2F10Bu2t and C10H3F10But.The X-ray crystal structure of the triphenyl derivative has been obtained.The 1H, 19F and 13C NMR data provide a satisfactory proof for the structures of the other compounds.
