Reactions singlet oxygen

In conclusion, singlet oxygen plays a role in the photo-oxidative degradation of polymers containing olefinic unsaturations. Polymers that do not contain these groups, e.g. poly(vinyl chloride), poly(methyl methacrylate), polystyrene, etc., are unreactive [24]. [Pg.202]


This group is prepared by the reaction of the anion of 9-hydroxyanthracene and the tosylate of an alcohol. Since the formation of this group requires an S 2 displacement on the alcohol to be protected, it is best suited for primaiy alcohols. It is cleaved by a novel singlet oxygen reaction followed by reduction of the endo-peroxide with hydrogen and Raney nickel. [Pg.65]

From singlet oxygen reaction with silyl enol ethers When a carbon tetrachloride solution of 1-methoxy-l-trimethylsiloxy-l-alkene in the presence of tetraphenylporphyrin and bubbling oxygen is irradiated with a 400-W Na lamp, a-trimethylsilyl peroxyesters were obtained in good yield (equation 11) . ... [Pg.779]

Although aUcenes react rapidly with singlet oxygen, reaction with triplet oxygen is normally slow. Exceptions are very electron-rich aUcenes such as tetraaminoethylenes , and normal aUcenes with low-lying triplet states such as cyclobutadienes andketenes . [Pg.819]

The addition of O2 (whether or A ) to 138 or 4 has apparently not been studied theoretically although selection rules for singlet oxygen reactions/ interpretation of substituent effects and orbital correlations for homolytic fission and re-formation of the peroxide bond in 9,10-diphenyl-anthracene peroxide and rubrene peroxide have been published. [Pg.203]

However, it is evident that the products of the singlet oxygen reaction with azoisobutane are not those of the photo-oxidation of the azoisobutane. [Pg.65]

For the sensitized oxidation, the rate of production of the oxidized substrate, that is, the rate of the chemical reaction of singlet oxygen, depends on the efficiencies of singlet oxygen production and singlet oxygen reaction (Eqs. 49 and 50). [Pg.274]
