在弱碱性条件下,双核钌(Ⅲ)配合物Ru2(DMBA)4(NO3)2(DMBA=tetrakis-N,N′-dimethylbenzamidinate)与不同芳香炔反应(其中芳香基团包括:NAPme,N-甲基-1,8-萘二甲酰亚胺;NAPiso,N-异丙基-1,8-萘二甲酰亚胺;Naphth,萘;Ant,蒽),制备了相应的端基炔取代配合物trans-Ru2(DMBA)4(C2Ar)2(Ar=NAPme,1;NAPiso,2;Naphth,3;Ant,4)。利用X射线晶体衍射测定了它们的结构。所有化合物的Ru-Ru键长处于单键范围(0.245 0~0.249 1 nm),它们均是抗磁性物质。进一步通过1H NMR和UV-Vis-NIR光谱进行了表征。电化学研究表明,所有化合物显示出与芳香基团有关的2个可逆的单电子氧化还原过程(包括一个氧化过程和一个还原过程)。
Under mildly alkaline condition, the complex of Ru2 (DMBA) 4 (NO3) 2 (DMBA = tetrakis-N, N’-dimethylbenzamidinate) with different aromatic alkynes (the aromatic groups include NAPme, N Naphthalene dicarboximide; NAPiso, N-isopropyl-1,8-naphthalimide; Naphth, naphthalene; Ant, anthracene) to prepare the corresponding end alkyne Substitution of the complex trans-Ru2 (DMBA) 4 (C2Ar) 2 (Ar = NAPme, 1; NAPiso, 2; Naphth, 3; Ant, 4). Their structures were determined by X-ray crystallography. The Ru-Ru bonds of all the compounds are in the single bond range (0.245 0 ~ 0.249 1 nm), and they are all diamagnetic materials. Further characterization by 1H NMR and UV-Vis-NIR spectroscopy. Electrochemical studies showed that all the compounds showed two reversible one-electron redox processes involving an aromatic group (including an oxidation process and a reduction process).
