Geometric and electronic structures of five-coordinate manganese(ii) "picket fence" porphyrin complexes.
Three five-coordinate, high spin manganese(ii) "picket fence" porphyrin complexes, [Mn(TpivPP)(L)] (TpivPP = α,α,α,α-tetrakis(o-pivalamidophenyl)porphyrinato; L = 1-MeIm (1-methylimidazole), 1-EtIm (1-ethylimidazole) and 2-MeHIm (2-methylimidazole)), are synthesized and studied by single-crystal X-ray, UV-vis and electronic paramagnetic resonance (EPR) spectroscopy. Structural parameters are in...
متن کاملStructure and Photochemistry of Manganese Porphyrin Sulfate Complexes
New sulfate and hydrogen sulfate complexes of metalloporphyrins have been synthesized and crystallographically characterized and their photochemistry examined. Irradiation of [Mn(TPP)],(SO,) and Mn(TPP)(OS03H) (where TPP = 5,10,15,20-tetraphenylporphyrinate(2-)) produces Mn"(TPP) quantitatively, with quantum yields of 7.1 X IO4 and 9.8 X IO-', respectively. In contrast to other manganese oxoani...
متن کاملSynthesis, characterization, and reactivities of manganese(V)-oxo porphyrin complexes.
The reactions of manganese(III) porphyrin complexes with terminal oxidants, such as m-chloroperbenzoic acid, iodosylarenes, and H(2)O(2), produced high-valent manganese(V)-oxo porphyrins in the presence of base in organic solvents at room temperature. The manganese(V)-oxo porphyrins have been characterized with various spectroscopic techniques, including UV-vis, EPR, 1H and 19F NMR, resonance R...
متن کاملHydrogen-atom abstraction reactions by manganese(V)- and manganese(IV)-oxo porphyrin complexes in aqueous solution.
High-valent manganese(IV or V)-oxo porphyrins are considered as reactive intermediates in the oxidation of organic substrates by manganese porphyrin catalysts. We have generated Mn(V)- and Mn(IV)-oxo porphyrins in basic aqueous solution and investigated their reactivities in C-H bond activation of hydrocarbons. We now report that Mn(V)- and Mn(IV)-oxo porphyrins are capable of activating C-H bo...
متن کاملThe binding assessment with human serum albumin of novel six-coordinate Pt(IV) complexes, containing bidentate nitrogen donor/methyl ligands
The interactions between platinum complexes and human serum albumin (HSA) play crucial roles in the distribution, metabolism, and activity of platinum-based anticancer drugs. Octahedral platinum (IV) complexes represent a significant class of anticancer agents that display molecular pharmacological properties different from cisplatin. In this study, the interaction between two Pt(IV) complexes ...
