| Questions And Answer | Back Directory | [Synthesis]
2,4,6-TRIPHENYLPYRYLIUM TETRAFLUOROBORATE can be prepared from acetophenone and benzaldehyde via a one-step reaction. 
Under nitrogen protection, a mixture of acetophenone (24.0 g, 0.2 mol), benzaldehyde (10.6 g, 0.1 mol), and BF3·Et2O (3.0 mL) was heated to 100 °C and reacted for 2 h. After cooling to room temperature, an appropriate amount of diethyl ether was added, the precipitate was filtered, washed with diethyl ether, and dried to give yellow crystals, with a yield of 65%. |

| Hazard Information | Back Directory | [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. |
