The preparation of quaternary 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 dipyrido[1,2-a: 3′,4′-c]pyrrole
