Trityl ethers are selectively cleaved by cerium(III) chloride in high yields in refluxing acetonitrile under neutral reaction conditions. The method is compatible with other acid sensitive functional groups like acetonide, acetate, benzoate, BOC, Cbz, benzyl, TBDPS, PMB, allyl, methyl and tetrahydropyranyl ethers present in the molecule.
