2-(Pyridinium-1-yl)-1,1-bis(perfluoroalkylsulfonyl)ethan-1-ide: A Practical Reagent for Synthesis of Strongly Acidic 1,1-Bis(perfluoroalkylsulfonyl)alkanes

On mixing (RfSO2)2CH2 (Rf=perfluoroalkyl), paraformaldehyde, and substituted pyridines, a three-component reaction proceeded smoothly to give unusual zwitterions bearing both pyridinium and stabilized carbanion moieties in good to excellent yields. Of these, 2-fluoropyridinium derivatives rapidly dissociated in acetonitrile to give equilibrium mixtures of the zwitterions and (RfSO2)2C=CH2/2-fluoropyridine, as confirmed by detailed variable-temperature NMR studies. The dynamic behavior of such 2-fluoropyridinium compounds allows them to be used as shelf-stable, easy-to-handle sources of (RfSO2)2C=CH2. With these reagents, strongly acidic carbon acids (RfSO2)2CHR were synthesized, which served as a new type of acid catalysts. Moreover, C?C bond-forming reactions with a ketene silyl acetal proceeded efficiently with Tf2C=CH2 generated in situ.

Catalyst system containing a fluorinated acid and a polyvalent tin compound
