) is used as a sensitizer to carry out the photo oxidation of cathecol. It is also used in the preparation of three N-alkylpyridinium photosensitizers by reacting with (1R,2S)-(-)-norephedrine, (S)-(+)-2-(aminomethyl)pyrrolidine and (R)-(-)-1-cyclohexylethylamine.

Amines react with pyrylium salts to give N-alkylpyridinium salts. Since the pyridine can be displaced by a variety of nucleophiles, the result is that the amine has been converted to a useful alkylating species: J. Chem. Soc., Perkin 1, 418 (1979).
