A four-electron oxidation of meso-octaethylporphyrinogen (H4L′) involving the dealkylation of two meso carbons has been observed in the reaction between [Ru(Cl)2(PhCN)4] and [Li4L′(THF)4] leading to [RuL(PhCN)2] which contains two hemiporphyrin fragments joined by two sp3 carbons, as shown by an X-ray analysis.
在[Ru(Cl)2(PhCN)4]和[Li4L′(THF)4]的反应中,已观察到中间八乙基卟啉原(H4L′)的四电子氧化,其中涉及两个中间碳的脱烷基化,最终生成[RuL(PhCN)2],其中包含两个由两个sp3碳连接起来的半卟啉片段,如X射线分析所示。
