Based on the investigations of the co゛dsorption behavior of acetophenone and hydrogen, we conclude that keto〆nol tautomerization occurs in the intramolecular process and does not involve hydrogen transfer through the surface hypothesized previously.doi:10.1002/ange.201808453...

The alkyl keto-diketones undergo photoinduced tautomerization mainly in the triplet state to the enol in acetonitrile. The alkyl enol-diketones, thus formed, undergo thermal tautomerization to the original keto forms in a few days. The alkyl enol-diketones show fast internal conversion from the ...
