Conclusions

  1. 1.

    1H and13C NMR spectroscopy was used to study the photoconversion of methyl n-propyl ketone, methyl benzyl ketone, and methyl adamantyl ketone. The13C and1H CIDNP signs indicated that the polarization arises upon the cleavage of excited ketones in the triplet state.

  2. 2.

    The competition of the radical photodecomposition (Norrish type-I) and “biradical” photodecomposition was studied in the photolysis of methyl n-propyl ketone. The ratio of the probabilities of the two radical pathways (recombination and disproportionation) is 3∶1, while the ratio of the two biradical pathways (photocyclization and Norrish type-II decomposition) is 3∶7.

  3. 3.

    A mechanism was established for the steps in the conversions of the radicals and radical pairs arising in the photolysis of the ketones studied.
