    • Application of Palladium-Mediated 18F-Fluorination to PET Radiotracer Development: Overcoming Hurdles to Translation 

      Kamlet, Adam; Neumann, Constanze Nicole; Lee, Eunsung; Carlin, Stephen M.; Moseley, Christian K.; Stephenson, Nickeisha A; Hooker, Jacob M; Ritter, Tobias (Public Library of Science, 2013)
      New chemistry methods for the synthesis of radiolabeled small molecules have the potential to impact clinical positron emission tomography (PET) imaging, if they can be successfully translated. However, progression of ...

    • A Dinuclear Palladium Catalyst for \(\alpha\)-Hydroxylation of Carbonyls with \(O_2\) 

      Chuang, Gary Jing; Wang, Weike; Lee, Eunsung; Ritter, Tobias (American Chemical Society, 2011)
      A chemo- and regioselective \(\alpha\)-hydroxylation reaction of carbonyl compounds with molecular oxygen as oxidant is reported. The hydroxylation reaction is catalyzed by a dinuclear Pd(II) complex, which functions as ...

    • A Fluoride-Derived Electrophilic Late-Stage Fluorination Reagent for PET Imaging 

      Lee, Eunsung; Kamlet, Adam Seth; Powers, David C.; Neumann, Constanze Nicole; Boursalian, Gregory Bagrad; Furuya, Takeru; Choi, Daniel C.; Hooker, Jacob M.; Ritter, Tobias (American Association for the Advancement of Science, 2011)
      The unnatural isotope fluorine-18 \((^{18}F)\) is used as a positron emitter in molecular imaging. Currently, many potentially useful \(^{18}F\)-labeled probe molecules are inaccessible for imaging because no fluorination ...

    • Silver-Mediated Trifluoromethoxylation of Aryl Stannanes and Arylboronic Acids 

      Huang, Chenghong; Liang, Theresa; Harada, Shinji; Lee, Eunsung; Ritter, Tobias (American Chemical Society, 2011)
      A silver-mediated cross-coupling of trifluoromethoxide with aryl stannanes and arylboronic acids to give aryl trifluoromethyl ethers is reported. This is the first report of a transition-metal-mediated \(C_{aryl}–OCF_3\) ...

    • Synthesis and Structure of Solution-Stable One-Dimensional Palladium Wires 

      Campbell, Michael Glenn; Powers, David C.; Raynaud, Jean; Graham, Michael J.; Xie, Ping; Lee, Eunsung; Ritter, Tobias (Nature Publishing Group, 2011)
      One-dimensional metal wires are valuable materials because of their optical and electronic anisotropy, and they have potential utility in devices such as photovoltaic cells and molecular sensors. However, despite more than ...
