TRIPHENYLCARBENIUM TETRAFLUOROBORATE Chemical Properties,Usage,Production

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 α?amino-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.
