 ochre-yellow to orange crystalline powder
 |  | [Uses] 
 
 Reactant involved in:
 Synthesis of substituted dihydroazulene photoswitchesCarbene-based Lewis pairs for hydrogen activation1,3-Dipolar cycloaddition reactions for preparation of α?amino-β-hydroxy estersOxidation of allenic compoundsMukaiyama aldol addition reactions Ionic hydrogenation as a counteranion and ligand source
 |  | [Uses] 
 Triphenylmethylium Tetrafluoroborate is reagent used in organic synthesis such as the direct synthesis of 1,1-diphenyl-3-arylindanes.
 |  | [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.
