无法鉴定的

Analogous complexes 3a" and 4a"= CpRu(PPh32, Ar = para-C6H4OMe containing methoxy group at the para-position of gem-diphenyl group were similarly obtained from protonation of the corresponding acetylide complexes via formation of vinylidene intermediate. But only complex 3a'= CpRu(PPh32, Ar2 = fluorenyl is stable in solution, and decomposed to unidentified complex when heated to reflux in THF. Deprotonation of complex 4a in the presence of base gives neutral acetylide complex 6a.

在两个相邻位置的苯基对位位置上接有一甲氧基的衍生物3a"和4a"也可利用类似的质子化反应合成，唯有错合物3a'= CpRu(PPh32， Ar2 = fluorenyl 可以稳定於溶液中，不会进行上述反应，如将其溶於四氢呋喃溶液加热至沸腾则会分解产生无法鉴定的化合物。

在两个相邻位置的苯基对位位置上接有一甲氧基的衍生物3a&和4a&也可利用类似的质子化反应合成，唯有错合物3a'= CpRu(PPh32， Ar2 = fluorenyl 可以稳定於溶液中，不会进行上述反应，如将其溶於四氢呋喃溶液加热至沸腾则会分解产生无法鉴定的化合物。

We use this technology to measure some rock and oil sample taken from Liaohe or Tarim basin. We identified many series of biomarker with dividing-era significance. These series are C26 steranes, C30 methylsteranes; and methly hopanoid alkanes, hexacyclic hopanoid alkanes, which two series were measured first by our laboratory in China.

本论文建立地球化学样品GOMS／MS分析方法；并对辽河盆地和塔里木盆地岩石及原油样品进行GC／MS／MS分析，鉴定出多个系列具有划时代意义的生标组分，这些组分是用GC／MS技术无法检测的极微量的生标组分：C26降胆甾烷系列、C30甲基甾烷系列等：还有高碳数甲基藿烷系列和六环藿烷系列见图1，图2，在国内被我们实验室首次检出。
