[Ru(II)(F(20)-tpp)(CO)] (1, F(20)-tpp=meso-tetrakis(pentafluorophenyl)porphyrinato dianion) was covalently attached to poly(ethylene glycol) (PEG) through the reaction of 1 with PEG and sodium hydride in DMF. The water-soluble PEG-supported ruthenium porphyrin (PEG-1) is an efficient catalyst for 2,6-Cl(2)pyNO oxidation and PhI==NTs aziridination/amidation of hydrocarbons, and intramolecular amidation
[Ru(II)(F(20)-tpp)(CO)](1,F(20)-tpp =间-四(五氟苯基)卟啉对二阴离子)通过1与PEG和氢化钠在DMF中的反应 水溶性PEG负载的钌卟啉(PEG-1)是2,6-Cl(2)pyNO氧化和PhI == NTs烃的叠氮化/酰胺化以及氨基磺酸酯与PhI(OAc)分子内酰胺化的有效催化剂)(2)。在CH(2)Cl(2),二恶烷或水中通过m-CPBA氧化PEG-1,得到了水溶性的PEG负载的二氧合钌(VI)卟啉(PEG-2),它可以与碳氢化合物反应以产生氧化产品的产率高达80%。两种PEG负载的钌卟啉配合物在水中的行为通过NMR光谱和动态光散射测量进行了探测。PEG-2对水非常稳定。
