Electrophilic substitution by pyrylium salts

  • Published:
Chemistry of Heterocyclic Compounds Aims and scope

Abstract

The reactions of various pyrylium salts with N-methylindole and dimethylaniline were studied. It is shown that the reactions are not restricted to electrophilic substitution but that hydride transfer to form a new pyrylium salt also occurs. The effect of anions on the character of the pyrylation is examined. The IR spectra of the compounds synthesized are presented.
