CAS Number:76-84-6
Molecular formula:C19H16O
Molecular Weight:260.33

Triphenylmethanol synthesis: Triphenylmethanol was prepared by the action of benzene with carbon tetrachloride in the presence of Aluminum chloride, followed by acidification and hydrolysis.
Triphenylmethanol can also be prepared by the reaction of phenylmagnesium bromide with methyl benzoate (instead of benzophenone).

Reaction Conditions:

with methanol;1,3-disulfonic acid imidazolium hydrogen sulfate at 20; for 0.0833333 h;Green chemistry;

Steps:

General procedure for the deprotection of trimethylsilyl ethers

General procedure: A mixture of the substrate (1 mmol), ionic liquid [Dsim]HSO4 (6.5 mg, ～0.02 mmol) in methanol (2 mL) was stirred at room temperature. After completion of the reaction (monitored by TLC), solvent was evaporated, water (1 mL) was added to the mixture, and stirred vigorously. Decantation of the mixture gave almost pure product(s). The products were characterized by comparison of their IR and NMR data. The ionic liquid was dried at 65 ?C under vacuum to remove moisture, and then reused.
