1、双核钌-DMBA双芳香炔化合物的合成和电化学性质(英文)SusannahD.BanzigerEileenC.JudkinsMatthiasZeller任彤DepartmentofChemistry,PurdueUniversity在弱碱性条件下,双核钌(III)配合物Ru2(DMBA)4(N03)2(DMBA=tetrakis~N,N'-dimethylbenzamidinate)与不同芳香炔反应(其中芳香基团拈: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
2、;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)o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(0.2450°.2491nm),它们均是抗磁性物质。进一步通过1HNMR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)。关键词:双核钌;炔基;1,8
