Urakawa, Kazuki; Kawabata, Yuta; Matsuda, Masaki; Sumimoto, Michinori; Ishikawa, Hayato published the artcile< α-Ketocarbenium Ions Derived from Orthoquinone-Containing Polycyclic Aromatic Compounds>, Computed Properties of 56724-03-9, the main research area is keto carbenium ion preparation orthoquinone PAH absorption spectra.
α-Ketocarbenium ions derived from synthesized orthoquinone-containing polycyclic aromatic compounds were generated in the presence of Bronsted acids such as sulfuric acid, trifluoromethanesulfonic acid, and fluorosulfonic acid. The prepared α-ketocarbenium ions were stabilized by conjugation of the aromatic moiety. In addition, unique absorption properties of the α-ketocarbenium ions were observed and identified on the basis of the calculated absorption spectra. It was suggested that the zigzag-shaped architecture stabilizes the newly discovered α-ketocarbenium ions derived from orthoquinone-containing polycyclic aromatic compounds
