Therefore, an immediate question arises: in transition-metal
nanoparticles stabilized by the self-assembly of 1-alkynes, will
such a dynamic equilibrium also exist at the metal−ligand
interface? This was addressed in the present study by taking
advantage of the specific reactivity of metal−vinylidene
complexes with imine derivatives to produce heterocyclic
azetidinylidene complexes (in fact, this is the method of choice
for identifying metal−vinylidene linkages in organometallic
complexes).Ruthenium nanoparticles stabilized by acetylide
derivatives were used as a comparative example. Because of
the lack of C−H protons, no Ru−vinylidene bond would be
anticipated to form at the nanoparticle interface, and thus, no
reacitivity with imine derivatives should be observed.

于是,一个直接的问题就来了: 通过1-炔自组装稳定化的过渡金属纳米粒子当中,在金属-配位体界面上也存在这样的动力平衡吗?这一问题在本研究中通过金属-亚乙烯基络合物与亚胺衍生物的特异反应生成杂环氮杂啶络合物而得到解决(实际上,这是在有机金属络合物中识别金属-亚乙烯基键所选择的方法)。经乙炔化衍生物稳定化的钌纳米粒子被用作对照样品。由于缺乏质子,预料在纳米粒子界面将不会有钌-亚乙烯基键形成,从而也就观察不到与亚胺衍生物的反应性。
