Triphenylmethylium Tetrafluoroborate is reagent used in organic synthesis such as the direct synthesis of 1,1-diphenyl-3-arylindanes.
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.
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.
