  摘要：

  21,23-Ditelluraporphyrins 3, 9, and 16-18 bearing phenyl, 4-methoxyphenyl, and/or 3,4, 5-trimethoxyphenyl meso substituents were prepared by the condensation of 2,5-di[hydroxy-(aryl)methyl]tellurophenes 12 with 2,5-di[2-pyrrolo(aryl)methyl]tellurophenes 15 in the presence of BF3 etherate followed by oxidation with p-chloranil. Compounds 15 were prepared from tellurophenes 12 with pyrrole and BF(3)-etherate Tellurophenes 12 were prepared in 44-72% isolated yield by the addition of 1,6-diarylhexa-2,4-diyn-1,6-diols 13 to the reduction product of Tc powder and LiBHEt(3). No additional Lewis acid was necessary in these reactions Coupling of 1-aryl-2-propyn-1-ols(14) with CuCl, pyridine, and air in MeOH gave diyndiols 13 26,28-Ditellurasapphyrin 10 was isolated in 0 6% yield from the reaction mixture that produced 9 in 12% isolated yield The X-ray structure of 10 showed a nearly planar sapphyrin core with the Te atoms of both tellurophene rings pointing to the center of the core 30,33-Ditellurarubyrin 11 was isolated in 32% yield by the reaction of two equivalents of trifluoroacetic acid with tellurophene dipyrrane 15c (125)Tc NMR spectra were recorded for the compounds of this study

  Pack more into the box: How to fit two metal ions in one porphyrin. Porphyrins’ default coordination mode allows the binding of a single metal cation in the central NNNN cavity. In order to allow the accommodation of two metal ions inside a standard porphyrin perimeter, they are introduced in place of two inner NH groups, yielding a 21,23-dimetallaporphyrin. The 18-π-electron aromatic circuit is maintained

  将更多的东西装入盒子中：如何将两个金属离子装入一个卟啉中。卟啉的默认配位模式允许在中央 NNNN 腔中结合单个金属阳离子。为了允许在标准卟啉周界内容纳两个金属离子，引入它们来代替两个内部 NH 基团，产生 21,23-二金属卟啉。 18-π-电子芳香环得以维持，在大环稳定和加强金属中心接近方面发挥着至关重要的作用。

  tellurophene rings, reacted with palladium(II), platinum(II), and rhodium(I) following two different paths. Palladium(II) formed bonds to two tellurium donors of the macrocycle, yielding a side-on coordination compound, with a square planar (Te2Cl2) metal ion environment. An alternative reaction path has been observed for ditelluraporphodimethene with platinum(II) or rhodium(I) in high boiling solvents

  Ditelluraporphodimethene 是一种含有两个碲吩环的非芳香族卟啉类化合物，它与钯 (II)、铂 (II) 和铑 (I) 按照两种不同的路径进行反应。钯 (II) 与大环的两个碲供体形成键，产生侧向配位化合物，具有方形平面 (Te 2 Cl 2) 金属离子环境。在高沸点溶剂中，已经观察到二碲卟啉二甲烯与铂 (II) 或铑 (I) 的替代反应路径。这些条件导致了深刻的转变，即一个碲原子与金属原子的交换，导致形成含有金属环戊二烯环的有机金属物种，即 21-platina-23-telluraporphodimethene 和 21-rhoda-23-telluraporphodimethene。取代反应选择性地在分子的共轭部分内的碲吩环上进行，即与两个 sp 2 内消旋碳原子结合的碲吩环。在铂金的情况下，交易所伴随着一个金币-芳基环与形成的铂环戊二烯环融合，铂（II）大环与氯
