Abstract
- We report the photocatalytic C-H amination of aromatics overcoming redox potential limitations. Radical cations of aromatic compounds are generated photocatalytically using Ru(phen) <subscript>3</subscript> (PF <subscript>6</subscript> ) <subscript>2</subscript> , which has a reduction potential at a high oxidation state ( E <subscript>red</subscript> (Ru <superscript>III</superscript> /Ru <superscript>II</superscript> ) = +1.37 V vs SCE) lower than the oxidation potentials of aromatic substrates ( E <subscript>ox</subscript> = +1.65 to +2.27 V vs SCE). The radical cations are trapped with pyridine to give N -arylpyridinium ions, which were converted to aromatic amines.
