1,1-bis(phenylsulfonyl)-1-(pyridinio)methanide

Abstract:
The title disulfonyl-stabilized pyridinium ylide, C5H5N+C-(SO2C6H5)(2) or C18H15NO4S2, contains a near planar NCS2 core. The structure suggests that the formal negative charge of the ylide C atom is delocalized to the S atoms rather than the N atom. Structural features of pyridinium ylides are briefly discussed.
