It is an alkyl halide, sometimes used to introduce the trityl protecting group.

Preparation

Triphenylmethyl chloride is commercially available. It may be prepared by the reaction of triphenylmethanol with acetyl chloride, or by the Friedel-Crafts alkylation of benzene with carbon tetrachloride to give the trityl chloride-aluminium chloride adduct, which is then hydrolyzed.

Reactions

Triphenylmethylsodium can be prepared from trityl chloride dissolved in an aprotic solvent and sodium: (C6H5)3CCl + 2 Na → (C6H5)3CNa + NaCl Reaction with silver hexafluorophosphate gives triphenylmethyl hexafluorophosphate.
