A direct pyridinium C-H sulfonylimination has been developed for the synthesis of sulfonyl iminopyridine derivatives I (R = H, CN, Ph, thiophen-2-yl, etc.; R1 = H, OMe, Ph, thiophen-3-yl, etc.; R2 = H, cyclopropyl, Ph, 4-bromophenyl, etc.; R1R2 = -CH=CH-CH=CH-; R3 = Me, Et, i-Pr, etc.; R4 = Et, Ph, pyridin-3-yl, etc.) with high efficiency. This transformation features the direct and efficient formation of a C=N bond with a high functional group tolerance under metal-free conditions. The spectroscopic properties potentially enable these sulfonyl iminopyridine compounds I to be useful new emitting materials.
