Synthesis and crystal structure of a bench-stable pyridinium ketene hemiaminal: 1-(1-eth­oxy­ethen­yl)-2-[meth­yl(phen­yl)amino]­pyridin-1-ium tri­fluoro­methane­sulfonate

ABSTRACT: The N-quaternized ketene N,O-acetal, 1-(1-eth­oxy­vin­yl)-2-(meth­yl(phen­yl)amino)­pyridin-1-ium tri­fluoro­methane­sulfonate was synthesized and its structure determined, making it a rare example of this class of compounds to be structurally characterized. The novel bench-stable N-quaternized ketene N,O-acetal, C16H19N2O+·CF3O3S−, was synthesized and its structure determined. The title compound is a rare example of a pyridinium ketene hemiaminal for which a crystal structure has been determined, joining the 2-chloro-1-(1-ethyoxyethen­yl)pyridin-1-ium tri­fluoro­methane­sulfonate salt from which it was synthesized. The cationic species of the title compound can be defined by three individually planar fragments assembling into a non-coplanar cation. The phenyl substituent extending from th
