Photochemical and Electrochemical Oxidation Reactions of Surface-Bound Polycyclic Aromatic Hydrocarbons
Mazur, Maciej,Blanchard
, p. 1038 - 1045 (2004)
The oxidation reactions of two PAH, i.e., pyrene and anthracene, attached covalently to silica, indium-doped tin oxide (ITO), and gold surfaces were studied. For both pyrene and anthracene, electrochemical and photochemical oxidation produced first a monohydroxy-PAH followed by the formation of dihydroxy/dione derivatives. Although the products of electrochemical or photochemical transformations were the same, the mechanism of each reaction might be different. In the case of electrochemical oxidation, no effect of oxygen dissolved in the solution on the voltammetric behavior was observed. The photodegradation of pyrene could occur through two paths, i.e., electron transfer and the reaction of pyrene with generated singlet oxygen. Singlet oxygen was not involved in the photochemical transformation of surface bound pyrene and the electron-transfer mechanism was dominant. The reaction of anthracene with water led to the formation of hydroxyanthracene and anthraquinones. The electron-transfer mechanism was dominant as the initial step of anthracene oxidation as well.
PHOTOREDUCTION AND PHOTOADDITION REACTIONS OF PYRENEDIONES

Upon irradiation with visible light the environmental pollutants 1,6-, 1,8- and 4,5-pyrenedione are reduced to the corresponding dihydroxypyrenes, while 4,5-pyrenedione undergoes photoaddition reactions with alkenes and sulfur dioxide.

Pyrenediones (PYDs) are efficient photocatalysts for three oxygenation reactions: Epoxidation of electron deficient olefins, oxidative hydroxylation of organoborons, and oxidation of sulfides via in situ generation of H2O2 under visible light irradiation, using oxygen as a terminal oxidant and IPA as a solvent and a hydrogen donor.

Photoinduced electron-transfer reactions of several ketone substrates were studied to evaluate the utilities of 1,6-bis(dimethylamino)pyrene (BDMAP), 1,6-dimethoxypyrene (DMP), 9,10-bis(dimethylamino)anthracene (BDMAA), and 9,10-dimethoxyanthracene (DMA) as electron-donating sensitizers cooperating with 2-aryl-1,3-dimethylbenzimidazolines. BDMAP and DMP generally led higher conversion of ketones and better yield of reduction products compared to BDMAA and DMA.
