Triphenylmethyl chloride or trityl chloride (TrCl) is a white to yellow solid. Insoluble in water, easily soluble in benzene, carbon disulfide, petroleum ether, slightly soluble in alcohol and ether, and becomes trityl alcohol after absorbing water. It is an alkyl halide, sometimes used to introduce the trityl protecting group.??
Trityl Chloride is an alkyl halide commonly used in organic synthesis to introduce the trityl protecting group. Trityl Chloride is used in the preparation of S-trityl-L-cysteine (STLC), a tight-bindin g inhibitor of Eg5 that prevents mitotic progression.?? ??
Triphenylmethyl Chloride acts as a protecting reagent for amines, alcohols, and thiols. It can be used as a catalyst:Efficient method of tritylation of sensitive compounds and their subsequent detritylation.
In Ritter type synthesis of 1-amidoalkyl-2-naphtols through a one-pot three-component reaction of naphthol, aryl aldehydes and acetonitrile.
In the synthesis of 1,2,4,5-tetrasubstituted imidazoles via a one-pot multi-component reaction of benzil with aldehydes, primary amines, and ammonium acetate.
In the preparation of amido alkyl phenols via one-pot, multi-component reaction of phenols, aromatic aldehydes, and amides under solvent-free conditions.
In one-pot, multi-component synthesis of substituted piperidines using aromatic aldehydes, amines, and β-ketoesters.
Purification Methods
Crystallise trityl chloride from iso-octane. Also crystallise it from 5 parts of pet ether (b 90-100o) and 1 part of acetyl chloride using 1.8g of solvent per g of chloride. Dry it in a desiccator over soda lime and paraffin wax. [Bachman Org Synth Coll Vol III 841 1955, Thomas & Rochow J Am Chem Soc 79 1843 1957, Moisel et al.
