Abstract

Pyrylium salts having π-electronic sextet and delocalized positive charge represent the particular class of aromatic compounds showing high reactivity. They are widely applied in organic syntheses and, on the other hand, are the naturally occurring plant compounds. This is why the chemistry of pyrylium salts has received a great deal of attention. This review will be generally confined to a discussion of certain reactions of pyrylium salts.
