  Synthesis and Spectral Properties of Unsymmetrically Substituted Mn(II) and Mn(III) Octaethylporphyrins

  摘要：

  5-Mononitro-2,3,7,8,12,13,17,18-octaethylporphyrin, 5,10,15-trinitro-2,3,7,8,12,13,17,18-octaethylporphyrin, and their Cd(II) complexes were synthesized. The coordination reactions of 2,3,7,8,12,13,17,18-octaethylporphyrin and its mono- and trinitro-substituted derivatives and the metal-exchange reactions of the synthesized Cd(II) octaethylporphyrin complexes with Mn(II) chloride in DMF were investigated by spectrophotometry. The corresponding Mn(II) and Mn(III) porphyrins were obtained and identified. The kinetic parameters of the studied reactions were determined.

  从 Taube 的开创性工作来看，1 电子转移反应可以在机械上分为内球或外球过程。在任何一种情况下，研究最充分的系统通常都涉及单电子变化。涉及多个电子转移的氧化还原过程，尤其是两种金属之间的转移，并不那么普遍，因此也不太了解。对多电子变化的最广泛研究涉及原子转移过程。2 这些通常是由桥接卤素 3•4 或桥接 oxo5 配体介导的两种电子转移反应。在氧化还原反应中将氮化配体作为桥连物质的考虑很少受到关注。6 在这方面，我们开始研究金属卟啉的氮化配合物的桥连能力。我们在此报告了由氮原子转移介导的可逆净三电子氧化还原过程的第一个例子。学科化学评论经美国化学学会杂志 111 (1989): 3755, doi:10.1021/ja00192a047 许可重印（改编）。版权所有 1989 美国化学学会。这篇文章可从爱荷华州立大学数字知识库获得：http://lib.dr.iastate.edu/chem_pubs/735

• Electrogeneration of Oxidized Corrole Dimers. Electrochemistry of (OEC)M Where M = Mn, Co, Ni, or Cu and OEC Is the Trianion of 2,3,7,8,12,13,17,18-Octaethylcorrole

  The electrochemistry of (OEC)M where M Mn, Co, Ni, or Cu and OEC is the trianion of 2,3,7,8, 12,13,17,18-octaethylcorrole was investigated in dichloromethane, benzonitrile, or pyridine, and the oxidized compounds were characterized by UV-visible and/or ESR spectroscopy. The first two oxidations of the Co, Ni, and Cu corroles involve the reversible stepwise abstraction of 1.0 electron per two (OEC)M units and lead to [(OEC)M](2)(+) and [(OEC)M](2)(2+), which are assigned as pi-pi dimers containing oxidized corrole macrocycles and divalent central-metal ions on the basis of the electrochemical and spectroscopic data. The ESR spectrum of [(OEC)Cu](2)(+) suggests the presence of one ESR-active Cu(II) center in the singly oxidized dimer. Further bulk electrooxidation of [(OEC)Cu](2)(+) at potentials positive of the second oxidation results in the abstraction of a second electron from the dimeric unit and leads to a triplet ESR spectrum typical of a copper(II) dimer, from which a Cu-Cu distance of 3.88 Angstrom is calculated. The ESR spectrum of [(OEC)Co](2)(+) in frozen CH2Cl2 at 77 K has a major line at g(perpendicular to) = 2.40 with a weak signal at g(parallel to) = 1.89 and is typical of a Co(II) ion. The doubly oxidized dimer, [(OEC)Co](2)(2+), is ESR silent in CH2Cl2 or PhCN, thus suggesting that the two unpaired electrons of the two Co(II) ions in [(OEC)Co](2)(2+) are coupled. The absolute potential difference between E-1/2 for generation of [(OEC)M](2)(+) and [(OEC)M](2)(+) can be related to the degree of interaction between the two (OEC)M units of the dimer and follows the order Co (Delta E-1/2 = 460 mV) > Ni (Delta E-1/2 = 260 mV) > Cu (Delta E-1/2 =; 140 mV). No evidence is seen for dimerization of (OEC)Mn after oxidation to its Mn(IV) form in the first electron-transfer step, and the occurrence of this metal-centered reaction may be the reason for the absence of dimerization.
