合成并研究了一种四个硼-二吡咯环共价取代的钌卟啉（BODIPY）。所得到的复合物显示出有效的脱羰基反应，主要是由于光诱导的能量转移过程。钌（II）BODIPY-卟啉的化学氧化提供了一个高能量的trans-dioxoruthenium（VI）物种，这是一个数量级以上的反应对烯烃氧化比那些类似物支持的常规卟啉。在可见光照射下，钌（II）BODIPY卟啉对二乙酸碘苯[PhI（OAc）2]和2，6-二氯吡啶N-氧化物（Cl 2 pyNO）分别作为终端氧化剂的硫化物氧化和烯烃环氧化反应表现出显著的催化活性.这项工作中的发现强调了卟啉-BODIPY共轭金属配合物对于可见光促进的催化氧化是潜在有用的。
A light-harvesting ruthenium porphyrin substituted covalently with four boron–dipyrrin (BODIPY) moieties has been synthesized and studied. The resulting complex showed an efficient decarbonylation reaction predominantly due to a photo-induced energy transfer process. Chemical oxidation of the ruthenium(II) BODIPY–porphyrin afforded a high-energy trans-dioxoruthenium(VI) species that is one order of magnitude more reactive towards alkene oxidation than those analogues supported by conventional porphyrins. In the presence of visible light, the ruthenium(II) BODIPY–porphyrin displayed remarkable catalytic activity toward sulfide oxidation and alkene epoxidation using iodobenzene diacetate [PhI(OAc)2] and 2,6-dichloropyridine N-oxide (Cl2pyNO) as terminal oxidants, respectively. The findings in this work highlight that porphyrin–BODIPY conjugated metal complexes are potentially useful for visible light-promoted catalytic oxidations.
