A direct pyridinium C–H sulfonylimination has been developed for the synthesis of sulfonyl iminopyridine derivatives 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 to be useful new emitting materials

Mono- and bispyridinium salts are shown to bind strongly with carboxylates in polar media through multiple hydrogen bonds and additional electrostatic interactions. The association constants of monopyridinium salt with various benzoates are in the range of 110-430 M-1 in DMSO-d(6), depending on substituents, while those between bispyridinium salts and adipate are >10(3) M-1 in 10% D2O/DMSO-d(6).
