Absolute rate constants of decay of aryl-substituted carbonyl oxides

Article abstract of DOI:10.1007/BF02496244

The decay kinetics of a series of carbonyl oxides (CbO) - 4-methylbenzophenone oxide, 2,5-dimethylbenzophenone oxide, 4-chlorobenzophenone oxide, 2-bromobenzophenone oxide, and acetophenone oxide - were studied by the pulse photolysis technique in acetonitrile, benzene, n-decane, and n-pentane. The absorption spectra were studied, and the absorption coefficients and absolute rate constants of CbO decay were determined. The absorption maxima observed in the spectra of carbonyl oxides range within 405±25 nm. The decay rate constant was found to depend on both the CbO structure and the medium.
