OXIDATION OF POLYSUBSTITUTED PYRIDINIUM SALTS

Oxidation of 1-substituted 2,4,6-triphenylpyridinium salts Ia-Ij with potassium ferricyanide in an alkaline medium was accompanied by contraction of the pyridine ring and formation of 1,2,3,5-tetrasubstituted pyrroles II.The derivative IIf underwent facil

Oxidation of 1-substituted 2,4,6-triphenylpyridinium salts

During the oxidation of 1,2,4,6-tetrasubstituted pyridinium salts 1 with potassium hexacyanoferrate(III) in alkali medium a contraction of pyridine ring is observed leading to 1,2,3,5-tetrasubstituted pyrroles 2.
