Autoignition=Triphenylmethyl chloride or trityl chloride is a white solid with the chemical formula C19H15Cl. It is an
alkyl halide , sometimes used to introduce the tritylprotecting group .Preparation
Triphenylmethyl chloride is commercially available. It may be prepared by the reaction of
triphenylmethanol withacetyl chloride , or by theFriedel-Crafts alkylation ofbenzene withcarbon tetrachloride to give the trityl chloride-aluminium chloride adduct, which is then hydrolyzed.
