| | TRIPHENYLCARBENIUM TETRAFLUOROBORATE Usage And Synthesis |
| Chemical Properties | ochre-yellow to orange crystalline powder | | Uses | Triphenylmethylium Tetrafluoroborate is reagent used in organic synthesis such as the direct synthesis of 1,1-diphenyl-3-arylindanes. | | Uses | Reactant involved in:
- Synthesis of substituted dihydroazulene photoswitches
- Carbene-based Lewis pairs for hydrogen activation
- 1,3-Dipolar cycloaddition reactions for preparation of αamino-β-hydroxy esters
- Oxidation of allenic compounds
- Mukaiyama aldol addition reactions
- Ionic hydrogenation as a counteranion and ligand source
| | Preparation | Preparative Methods of Triphenylcarbenium Tetrafluoroborate: the most convenient procedure involves the reaction of Ph3CCl with Silver(I) Tetrafluoroborate in
ethanol. The most economical route employs the reaction of Ph3CCl with the anhydrous Tetrafluoroboric Acid-Et2O
complex. | | storage | Triphenylcarbenium Tetrafluoroborate is moisture-sensitive and corrosive. Recrystallized reagent can be stored at rt for several
months in a desiccator without significant decomposition. This compound is much less light-sensitive than other trityl salts such
as the perchlorate. |
