Pyridium salts are very valuable compounds with various activities, especially biological, and therefore their preparation can be very useful in the synthesis of various compounds, such as drugs, dyes or surfactants. In this mini-review authors focused mostly on bioactive properties of pyridinium salts, and main preparations of these compounds such, synthesis pyridinium salts from pyrylium salts via nucleophilic substitution SN(ANRORC), obtaining pyridinium salts via directs arylation, and via Addition at Nitrogen atom, and the last method is synthesis of pyridinium salts via ring opening and re-cyclisation.
