Roessler, Simon L. published the artcilePyridyl Radical Cation for C-H Amination of Arenes, Product Details of C6H5F4NO3S, the publication is Angewandte Chemie, International Edition (2019), 58(2), 526-531, database is CAplus and MEDLINE.
Electron-transfer photocatalysis provides access to the elusive and unprecedented N-pyridyl radical cation from selected N-substituted pyridinium reagents. The resulting C(sp2)-H functionalization of (hetero)arenes furnishes versatile intermediates for the development of valuable aminated aryl scaffolds. Mechanistic studies that include the first spectroscopic evidence of a spin-trapped N-pyridyl radical adduct implicate SET-triggered, pseudo-mesolytic cleavage of the N-X pyridinium reagents mediated by visible light.
