Abstract
The syntheses of four binary porphyrins, two of which are constrained to a "face-to-face" conformation, and their Co2+ and Cu2+ derivatives are described. Electron spin resonance indicates that the intermetallic separation in the binuclear "face-to-face" porphyrins is about 6.5-6.8 A. Electronic spectra and proton magnetic resonance spectra support the postulated "face-to-face" conformations. A hypothesis that related compounds may serve as multielectron redox catalysts for O2 and N2 is presented.
摘要
本文描述了四种二元卟啉的合成方法，其中两种被限制为“面对面”构象，以及它们的Co2+和Cu2+衍生物。电子自旋共振表明，双核“面对面”卟啉中的金属间距离约为6.5 - 6.8埃。电子光谱和质子磁共振光谱支持假定的“面对面”构象。本文还提出了一个假设，即相关化合物可能作为O2和N2的多电子氧化还原催化剂。
