Abstract

In distinct contrast to metastable triarylethenol cation radicals, the corresponding isomeric ketones not only show site-specific reciprocal methyl/hydrogen migration but, in addition, some of them undergo hydrogen exchange reactions between the various aryl rings prior to dissociation. A brief discussion is presented for H₂O loss from ionized 1,2,2-trimesitylethanol and the gas-phase chemistry of the resulting trimesitylethene cation radical.
