1,2,3,5-Tetrakis(trifluoromethyl)benzene reacts with phenyl-lithium or t-butyl-lithium togive mixtures of de-aromatised products, derivatives of 2,5- and 2,4-cyclohexadiene-l-ylideneof molecular composition C10H2F10Ph2, C10H2F9Ph3, C10H2F10Bu2t and C10H3F10But.The X-ray crystal structure of the triphenyl derivative has been obtained. The 1H, 19Fand 13C NMR data provide a satisfactory proof for the
1,2,3,5-四(三氟甲基)苯与苯基芳烃或叔丁基锂得到的脱芳构化合物,2,5-和2,4-环己二烯-1-亚烷基衍生物的混合物C 10 H 2 F 10 Ph 2,C 10 H 2 F 9 Ph 3,C 10 H 2 F 10 Bu 2 t和C 10 H 3 F 10 Bu t。获得了三苯基衍生物的X射线晶体结构。 。的1个H,19 FAND 13C NMR数据为其他化合物的结构提供了令人满意的证据。
