Aerobic oxidation of alcohol by model complexes relevant to metal site galactose oxidase: role of copper(I) intermediate, evidence for the generation of end-on copper(II)–OOH species and catalytic promiscuity for oxidation of benzyl alcohol, catechol and o-aminophenol

Design and synthesis of dinuclear cobalt(ii) complexes derived from strong π-acidic ligands: crystal structure and studies on the oxidation of sp3 C–H bonds

“…Ligands Gimpy (here we denoted as L 1 ) and L 2 were synthesized according to the procedure previously reported in the literature. 37–39 Ligands were characterized by NMR, ESI-MS, UV-visible, and IR spectroscopic studies and the data were consistent with our previous report. 37–39 The electronic spectral data and spectrum for L 1 and L 2 are shown in the ESI† (Table S1 and Fig.…”

“…Ligand L 2 was synthesized according to the procedure previously reported in the literature. First, 0.545 g (5.0 mmol) 2-hydrazineylpyridine 39 was taken in a round-bottomed flask and dissolved in 10–15 mL methanol at room temperature. After that, a methanolic solution of 0.145 g (2.5 mmol) glyoxal was added and the mixture was stirred at room temperature.…”

Preparation of Ultrathin and Degradable Polymeric Films by Electropolymerization of 3‐Amino‐l‐tyrosine

“…The spectra are dominated by overlapping peaks centered at 340 nm, attributed to the conjugation of two ALT monomers, and at 430 nm, which have been attributed to the formation of phenoxazine structures in the oxidation of aminophenol. [ 44,45 ] Similar to poly(aminophenol) formation, phenoxazine structures could, in principle, serve as new monomers during the formation of PALT resulting in different polymeric structures compared to PNE and PDA. [ 31–33 ]…”

[31][32][33] In order to obtain a more comprehensive chemical analysis of the synthesized films, the Fourier transform infrared (FTIR) spectra of all three polymer coatings after ten cycles were recorded and are depicted in Figure S7 (Supporting Information).…”
