The stability of the radical zwitterions derived by electron addition to N-alkyl-2,4,6-triphenyl- and 4-phenylpyridinium salts has been examined.Rapid carbon-nitrogen bond cleavage occurs for benzyl and allyl substituents only when the 2,6-diphenyl substituents are present.The N-propyl group is not lost.Homologous N,N'-polymethylenebis(2,4,6-triphenylpyridinium) salts show two reversible one electron waves, distinct for the ethylene derivative and merging as the carbon chain lengthens so that ΔEo reaches the theoretical value of (RT/F) ln 4.
