1,1-bis(phenylsulfonyl)-1-(pyridinio)methanide.
The title disulfonyl-stabilized pyridinium ylide, C(5)H(5)N(+)-C(-)(SO(2)C(6)H(5))(2) or C(18)H(15)NO(4)S(2), contains a near planar NCS(2) 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.
