, p. 2273 - 2283 (2007/10/02)
Reduction of 3-cyanopyridinium salts has been studied on the mercury dropping electrode.Solvent and substituent effects and pH of the medium have been shown to modify in a certain extent differently the polarographic characteristic as compared with analogous 3-carbamoyl derivatives, which is due to higher electronegativity of the studied cations.
Investigations of Quarterny Pyridinium Salts, XI Reactions of Cyanopyridinium Salts with Hydroxylamine

, p. 896 - 901 (2007/10/02)
The preparation of quarternary pyridinium salts with amidoxime group in 2-, 3- and 4-position is described.The isomer with the substituent in 3-position rearranges on addition of base to a 1-hydroxy-2-imino-3-pyridinecarbaldimine.The reaction of 3-cyano-pyridinium salts with hydroxylamine and potassium tert-butoxide gives derivatives of dipyridopyrrole. - Keywords: Pyridinium Salts, Rearrangement, Condensation Reaction
Investigations of Quaternary Pyridinium Salts, X. A Condensation Reaction of 3-Cyanopyridinium Salts on Addition of Alcoxides
Guendel, Wolf-H.
, p. 490 - 493 (2007/10/02)
1-Benzyl-3-cyanopyridinium salts, in the benzyl moiety differently substituted, react in boiling alcohol with alcoxides to derivatives of hexahydro-dipyridopyrrole.At 20 deg C occurs rearrangement to derivatives of 2-amino-3-pyridinecarbald
