Pyridyl Radical Cation for C?H Amination of Arenes

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.

MECHANISM OF 1-PHENYL-1,4-DIHYDROPYRIDINE FORMATION IN REACTION OF 1-PHENYLPYRIDINIUM CHLORIDE WITH ALKALI METAL ALKOXIDES

Quaternary salt Ia reacts with sodium and lithium alkoxides to give 1-phenyl-1,4-dihydropyridine (IIIa) together with the unsaturated aldehyde IVa.The reaction mechanism for formation of compound IVa from the primarily arising 2-alkoxy-1-phenyl-1,2-dihydropyridines is suggested on the basis of products IIIb and IVb, arising from the 3,4,5-trideuterio precursor Ib.
