Spectroscopic evidence for a new type of bonding between a thioether radical cation and a phenyl group.

Nicolas P-A Monney1, Thomas Bally, Ganga S Bhagavathy, Richard S Glass.   

Abstract

The oxidation potential of thioethers constrained to be near aromatic rings is lowered, due to an antibonding interaction between the p-type sulfur lone pair with the neighboring phenyl π-system which on removal of an electron becomes a new kind of 3-electron S∴π bonding that reveals itself in the photoelectron spectrum and by an electronic transition involving the orbitals participating in the S∴π bond.
