有机配体如吡啶、咪唑等在TPPFe(Ⅲ)Cl,溶液中能分别形成TPPFe(Ⅲ)(L)Cl六配位配合物和TPPFe(Ⅲ)(L)_2~+Cl~-六配位络离子盐,洪华华等曾报道咪唑类有机配体的加入可提高环己烷在抗坏血酸-O_2-TPPFe(Ⅲ)Cl催化羟化反应体系中的环己醇产率。但有关有机配体对TPPFe(Ⅲ)Cl催化羟化烷烃性能的影响还未见系统研究报道,我们较系统地考察了不同有
Organic ligands such as pyridine and imidazole can form hexavalent coordination complexes TPPFe (Ⅲ) (L) Cl and TPPFe (Ⅲ) (L) _2 ~ + Cl ~ - hexacoordinate in TPPFe (Ⅲ) Cyanide salt, Honghua Hua et al. Reported that the addition of imidazole organic ligand could increase the cyclohexanol yield of cyclohexane in the reaction of ascorbic acid-O_2-TPPFe (Ⅲ) Cl catalyzed hydroxylation. However, the effect of organic ligands on the catalytic properties of TPPFe (III) Cl for hydroxylation of alkanes has not been reported systematically. We systematically investigated the effects of different
