The title compound (H2tpsac) was synthesized from 6-bromosaccharin and 3,3’’-bis(bromomethyl)- m-terphenyl. The ability of tpsac to serve as a tetradentate bis-bridging ligand was demonstrated by the formation of the dinuclear ruthenium(I,I) complexes [Ru2(CO)5(μ,μ-tpsac)]2, [Ru2(CO)4(μ,μ-tpsac)]n, [Ru2(CO)4(PPh3)2(μ,μ-tpsac)], and [Ru2(CO)5(PPh3)(μ,μ-tpsac)]. An X-ray crystal structure analysis of [Ru2(CO)4(PPh3)2(μ,μ-tpsac)] showed the head-to-tail (or 1,1) arrangement of the two saccharinate coordination sites.
标题化合物(H2tpsac)是由 6-溴糖精和 3,3''-双(溴甲基)间三联苯合成的。通过形成双核钌(I、I)配合物[Ru2(CO)5(μ,μ-tpsac)]2、[Ru2(CO)4(μ,μ-tpsac)]n、[Ru2(CO)4(PPh3)2(μ,μ-tpsac)]和[Ru2(CO)5(PPh3)(μ,μ-tpsac)]。对[Ru2(CO)4(PPh3)2(μ,μ-tpsac)]的 X 射线晶体结构分析表明,两个糖醛酸配位位点呈头对尾(或 1,1)排列。
