Popis:	By the reaction of lithium derivatives of cyclopentadienylmagnesiumtricarbonyl, cyclopentadienylrheniumtricarbonyl, and benzenechromiumtricarbonyl with 2,6-disubstituted pyrylium salts the corresponding 4H-pyrans have been synthesized, and the oxidative dehydration of these has given pyrylium cations containing the stated organometallic groups in position 4. It has been shown that the π-complexes obtained readily exchange the oxygen of the pyrylium ring for other heteroatoms with the formation of heterocyclic compounds with metallocarbonyl substituents.
