Radical Transport Reaction. Concurrent Transfer of Electron and Proton

Article abstract of DOI:10.1246/bcsj.61.2923

Concurrent transport of electron and proton on the same molecule; formal hydrogen-transfer reaction, is succesfully realized in aprotic media by using 1-butyl-4,4'-bipyridinium cation radical (BuPPH*⁺), which is prepared from 1-butyl-4-(4-pyridyl)pyridinium ion.Hydrogen reduction with BuPPH*⁺ was discriminated from electron reduction with octylviologen cation radical by the chemoselective reduction preferring enedione to vic-dibromide in aprotic media.
