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 (1
R ,2
S )-(-)-norephedrine, (
S )-(+)-2-(aminomethyl)pyrrolidine and (
R )-(-)-1-cyclohexylethylamine.
