Mechanically induced C−C bond formation was demonstrated by the laser driven shock wave generated in liquid normal alkanes at room temperature. Gas chromatography mass spectrometry analysis revealed the dehydrogenation condensation between two alkane molecules, for seven normal alkanes from pentane to undecane. Major products were identified to be linear and branched alkane molecules with double the number of carbons, and exactly coincided with the molecules predicted by supposing that a C−C bond was formed between two starting molecules. The production of the alkane molecules showed that the C−C bond formation occurred almost evenly at all the carbon positions. The dependence of the production on the laser pulse energy clearly indicated that the process was attributed to the shock wave. The C−C bond formation observed was not a conventional passive chemical reaction but an unprecedented active reaction.

激光驱动冲击波机械 C−C 键形成
室温下液态正烷烃中产生的激光驱动冲击波证明了机械诱导的 C−C 键形成。气相色谱质谱分析揭示了从戊烷到十一烷的七种正构烷烃在两个烷烃分子之间的脱氢缩合。主要产物被鉴定为具有双倍碳原子数的直链和支链烷烃分子，并且与假设两个起始分子之间形成CC键所预测的分子完全一致。烷烃分子的生成表明，CC 键的形成几乎均匀地发生在所有碳位置上。生产对激光脉冲能量的依赖性清楚地表明该过程归因于冲击波。观察到的CC键形成不是传统的被动化学反应，而是前所未有的主动反应。
