title: 2-(Pyridinium-1-yl)-1,1-bis(triflyl)ethanides: structural behaviour and availability as bis(triflyl)ethylating reagents.
abstract: Stable and easy-to-handle zwitterions containing carbanion and pyridinium moieties were synthesized, and their structural studies by both X-ray crystallography and theoretical methods revealed the stereoelectronic effect in the zwitterionic 'C(-)-C-N(+)' system.
