  通过点击反应对有机金属配合物进行后功能化

  摘要：

  CuAAC（Cu catalyzed azide-alkyne cycloaddition）点击反应是一种简单而有效的过渡金属有机金属配合物的合成后修饰方法。这种方法允许选择性地将额外的供体位点或官能团引入配体环境的外围。如果必须创建具有与主要金属配位的主要位点相同性质的自由供体位点的金属配体，这一点尤其重要。通过点击反应对有机金属配合物进行合成后修饰的概念相对较新，目前可用的实验材料还不能让我们确定趋势并制定解决具体问题的建议。在目前的研究中，

  Heteroheptanuclear ReM6 (M = Cu 2, Ag 3) complexes of 5,5-diethynyl-2,2 '-bipyridine were prepared by the reaction of [M-2(mu-dppm)(2)(MeCN)(2)](2+) (dppm = bis(diphenylphosphino)methane) with the precursor compound Re( Me3SiC equivalent to CbpyC equivalent to CSiMe3)(CO)(3)Cl in the presence of potassium fluoride by fluoride-catalyzed desilylation. When [Cu-2(mu-dppm)(2)(MeCN)(2)](2+) reacts directly with Me3SiC equivalent to CbpyC equivalent to CSiMe3, a binuclear Cu-I complex [Cu-2(mu-dppm)(2)( SiMe3C equivalent to CbpyC equivalent to CSiMe3)(2)](2+) (4) was isolated. Further addition of [Cu-2(mu-dppm)(2)(MeCN)(2)](2+) into a THF-MeOH (3:1, v/v) solution of 4 in the presence of potassium fluoride induced isolation of a tetradecanuclear Cu-14(I) complex [Cu-14(mu-dppm)(14)(C equivalent to CbpyC equivalent to C)(2)](10+), which is composed of a binuclear Cu-2(mu-dppm)(2) and four triangular trinuclear Cu-3 units. Both heteroheptanuclear (ReM6I)-M-I and tetradecanuclear Cu-14(I) complexes display luminescence in both solid states and dichloromethane solutions at room temperature with emissive lifetimes in the range of microseconds. The dual emissive feature for the ReM6 and Cu-14(I) complexes is ascribed tentatively to originate from both MLCT [d(Re/Cu) -> pi* (bpy)] and LMCT (acetylide -> M-3) transitions.

  We report here on ruthenium alkenyl complexes 2 and 3 derived from 2,2'-bipyridine and their Re(CO)(3)X adducts 4a,b and 5. Detailed electrochemical studies on these complexes and spectroscopic characterization of their oxidized forms by IR, UV/vis/NIR, and electron paramagnetic resonance spectroscopies as well as quantum chemical studies reveal sizable (bridging) ligand contributions to the redox orbitals. Engagement of the free bipy functions of complexes 2 and 3 in binding to the electron-withdrawing fac-Re(CO)(3)X (X = Br, Cl) moiety enhances the metal-to-ligand charge-transfer character of the optical excitations, causes sizable anodic shifts of the redox potentials, and decreases the number of observable anodic redox waves by one when compared to complexes 2 and 3. Despite the decreasing electron density at the terminal or bridging alkenyl bipyridine ligand, the anodic redox processes still maintain appreciable ligand character as is seen by the shifts of the Ru(CO) and Re(CO)(3) stretching frequencies on oxidation. Binding of the fac-Re(CO)(3)X moiety also attenuates the degree of ground-state delocalization in the mixed-valent states.
