| | 2,4,6-TRIPHENYLPYRYLIUM TETRAFLUOROBORATE Usage And Synthesis |
| Description | 2,4,6-Triphenylpyrylium Tetrafluoroborate converts primary amines into pyridinium salts which on reaction with nucleophiles NuH afford R-Nu. | | Chemical Properties | Yellow crystalline powder | | Uses | 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. | | reaction suitability | reaction type: Photocatalysis
reagent type: catalyst | | storage | may be stored indefinitely. Reports on possible mutagenic activity make it desirable to avoid direct contact with skin. |
