Selective C(sp) -H activation is of fundamental importance in processing alkane feedstocks to produce high-value-added chemical products. By virtue of an on-surface synthesis strategy, we report selective cascade dehydrogenation of -alkane molecules under surface constraints, which yields monodispersed all- conjugated polyenes with unprecedented length controllability. We are also able to demonstrate the generality of this concept for alkyl-substituted molecules with programmable lengths and diverse functionalities, and more importantly its promising potential in molecular wiring.
选择性C(sp) -H活化在将烷烃原料加工成高附加值化学产品方面具有至关重要的意义。借助表面合成策略，我们报道了在表面限制下直链烷烃分子的选择性级联脱氢反应，该反应可生成具有前所未有的长度可控性的单分散全共轭多烯。我们还能够证明这一概念对于具有可编程长度和多样功能的烷基取代分子的通用性，更重要的是其在分子布线方面的广阔潜力。
