Application

2,4,6-Triphenylpyrylium tetrafluoroborate was used as a sensitizer to carry out the photooxidation of cathecol. It was also used in the preparation of three N-alkylpyridinium photosensitizers by reacting with (1R,2S)-(-)-norephedrine, (S)-(+)-2-(aminomethyl)pyrrolidine and (R)-(-)-1-cyclohexylethylamine.

Three N-alkylpyridinium photosensitizers having chiral alkyl groups have been prepared by reacting 2,4,6-triphenylpyrylium tetrafluoroborate ion with (1R,2S)-(-)-norephedrine, (S)-(+)-2-(aminomethyl)pyrrolidine, and (R)-(-)-1-cyclohexylethylamine. Laser flash photolysis allows detection of the corresponding triplet excited states that are quenched by hydrogen atom donors and electron
