The synthesis and characterization of tritopic ligands, obtained by connecting two terpyridines or two bipyridines with a bis-substituted-ethynyl-bipyridine or bis-substituted-ethynyl-phenanthroline spacer are described. Palladium(0) catalyses the coupling of the bis-ethynyl substituted central spacer with a bromo or a triflate functionalized bipyridine or terpyridine subunit. A novel trinuclear ruthenium
描述了通过将两个三联吡啶或两个联吡啶与双取代的乙炔基联吡啶或双取代的乙炔基菲咯啉间隔基连接而获得的三位配体的合成和表征。钯(0)催化双乙炔基取代的中心间隔基与溴或三氟甲磺酸酯官能化联吡啶或三联吡啶亚基的偶联。还描述了新型三核钌(II)配合物。
