Efficient continuous-flow HD exchange reaction of aromatic nuclei in D2O/2-PrOH mixed solvent in a catalyst cartridge packed with platinum on carbon beads

Herein, a continuous-flow deuteration methodology for various aromatic compounds is developed based on heterogeneous platinum-catalyzed hydrogen-deuterium exchange. The reaction entails the transfer of a substrate dissolved in a mixed solvent of 2-propanol and deuterium oxide into a catalyst cartridge packed with platinum on carbon beads (Pt/CB). Pt/ CB could be continuously used without significant deterioration of catalyst activity for at least 24 h. Deuteration proceeded within 60 s of the substrate solutions being passed through the Pt/CB layer in the Pt/CB-packed cartridge.

Efficient and selective Pt/C-catalyzed H-D exchange reaction of aromatic rings

An effective and applicable deuteration method for aromatic rings using Pt/C-D2O-H2 system was established. Especially, phenol was fully deuterated even at room temperature, and other electron-rich aromatic nuclei were efficiently deuterated under mild conditions. The scope and limitations of the presence method and its application to the synthesis of deuterium-labeled biologically active compounds and deuterium-labeled building blocks for practical multi-gram scale syntheses are reported. 2008 The Chemical Society of Japan.

Uranyl-Sensitized Photochemical Oxidation of Naphthalene by Molecular Oxygen. Role of Electron Transfer

Naphthalene quenches the excited state *UO2(2+) in two parallel pathways: oxidation to naphthalene radical cation, C10H8(.+) (Φ = 0.3), and exciplex formation.The overall rate constant in aqueous acetonitrile containing 0.1 M H3PO4 has a value kq = 2.20E9 M-1 s-1.In the presence of O2, a portion of c10H8(.+) is converted to 2-formylcinnamaldehyde and several other products, the rest reacting with UO2(1+) by back electron transfer.
