Guendel, Wolf-H.
, 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
