Synthesis, characterization, and catalytic activity for thioanisole oxidation of homogeneous and heterogeneous binuclear manganese(II) complexes with amino acid-based ligands

Polymeric ionic liquid material‐anchored Mn–porphyrin anion: Heterogeneous catalyst for aerobic oxidation of olefins

“…[42] In the FT-IR spectrum of p(APTMACl)-[Mn(TPPS)(OAc)] (Figure 1c), compared to Figure 1(a), due to interaction between [Mn(TPPS) (OAc)] and hydrogel matrix, a shift of some bands was observed. In addition, the appearance of new bands at 1139, 621 and 466 cm −1 could be attributed to SO 3 group, [43] Mn─O bond and Mn─N bond, [44] respectively. Generally, for the FT-IR spectrum of p(APTMACl)-[Mn(TPPS) (OAc)], the appearance of bands corresponding to TPPS and Mn─M confirm that porphyrin has been embedded into the p(APTMACl) hydrogel.…”

Metal complexes of amino acids and peptides

“…92 In another study, Cu(II) complexes of bis(imidazol-2-yl) as superoxide dismutase (SOD) models have been investigated. 97 Mo(VI)-and V(IV)-containing complexes of His 98 or Lys and Met 99 showed the best activity in the oxidation reaction of cyclohexene in comparison with complexes of these amino acids with many other transition metal ions. 94 In the same laboratory, SOD inspired Ni(II)-amino acid complexes, covalently grafted onto Merrifield's resin, have also been prepared during the past two years.…”

Selective oxidation of sulfides and hydrocarbons with H$_{2}$O$_{2}$ over manganese catalyst supported on nanoparticles

“…20 For this purpose, a mixture of L -tyrosine (0.36 g, 2.0 mmol) and NaOH (0.08 g, 2.0 mmol) in CH 2 Cl 2 (10 mL) was added to a solution of salicylaldehyde (0.244 g, 2.0 mmol) in CH 2 Cl 2 (10 mL) and refluxed, whereupon the colorless solution rapidly turned yellow. …”
