Abstract
Using acetylacetone as an example, it was shown that the intramolecular hydrogen bond significantly affects the radiolytic transformations of organic compounds, suppressing the transfer of a proton from the primary radical cation to the molecule, and also contributing to the cleavage of the C–OH bond in the enol form. Due to these effects, the main heavy product of radiolysis at 295 K is 4-oxopent-2-en-2-yl acetate. Under boiling conditions (413 K), hydrogen bonds are eliminated, leading to the predominant formation of 4-hydroxy-2-pentanone, which is not detected at 295 K.
