标题配合物已被制备并通过光学、核磁共振、红外光谱和电化学进行表征。电化学表明该材料在卟啉环处经历了两个还原过程。这些过程的潜力表明它们是已报道的最简单的卟啉环还原反应。这些还原的容易性归因于高电荷 P (V) 离子的感应效应以及可能的结构因素。该配合物的单电子还原产生稳定的环还原自由基，该自由基已被分离和表征。添加第二个电子会通过内部电子转移产生游离碱四苯基卟啉等产物。
The title complex has been prepared and characterized by optical, NMR, and IR spectroscopy and electrochemistry. The electrochemistry reveals that this material undergoes two reductive processes at the porphyrin ring. The potential of these processes demonstrates that these are the easiest porphyrin-ring reductionsyet reported. The ease of these reductions is attributed to the inductive effects of the highly charged P (V) ion and perhaps structural factors as well. One-electron reduction of the complex leads to a stable ring-reduced radical, which has been isolated and characterized. Addition of a second electron leads to, among other products, free-base tetraphenylporphine via an internal electron transfer.
