Aerobic oxidation of phenols and related compounds using carbon nanotube-gold nanohybrid catalysts

Gold nanoparticles supported on carbon nanotubes were investigated as catalysts in the aerobic oxidation of various substrates (phenols, hydroquinones, catechols, aminophenols, and thiols). The nanohybrid system compares favorably with other supported noble metal catalysts in terms of overall efficacy as it operates at room temperature, under air atmosphere (no external oxidant needed), and can readily be recycled. Coming up for air: Gold nanoparticles supported on carbon nanotubes were investigated as efficient catalysts in the catalytic aerobic oxidation of phenol-type compounds.

Solid-state oxidation of phenols by tetrabenzopentacene endoperoxide

Solid state oxidation of phenols with TBPA-O2 were examined. Depending on the electron-releasing ability of p-substituents of phenols, different products were obtained. In the case of p-alkylphenols, successive proton transfers occur from the phenols to TBPA-O2 to give phenolate anions and a π-delocalized cation. They are coupled to give 6,15-diaryloxy TBPA. On the other hand, in the case of phenols with electron-releasing substituents (e.g. p-SCH3, p-OCH3), there occurs an electron transfer from a phenolate anion to a π-delocalized cation which are formed through proton transfer from the phenol to TBPA-O2. The resulted phenoxy radicals are coupled to afford dimeric products of them. Replacing process of included solvent in the crystal of TBPA-O2 with the substrate was monitored by a powder X-ray diffraction method.

PHOTOSENSITIZED DIMERIZATION OF PHENOL IN PORPHYRIN-QUINONE-PHENOL SYSTEM

Photosensitized dimerization of 4-methoxyphenol was observed upon irradiation of porphyrin in the presence of quinone.Quantum yield for dimer was depended upon the concentration and reduction potential of quinones used.Free radical coupling mechanism was confirmed by means of ESR and CIDNP techniques.
