Abstract
Ferricyanide oxidation of pyridinium salts Ia, Ib leads to mixture of isomeric heterocyclic ketones IIa, IIb and IVa, IVb, respectively. Crystal and molecular structures of the products IIb and IVb were determined by X-ray diffraction analysis. Formely presumed formation of heterocyclic systems type of the III type has been corrected.
