4,4'-Dimethoxytrityl chloride Chemical Properties,Uses,Production

Chemical Properties

4,4'-Dimethoxytrityl chloride is pink powder

Uses

4,4'-Dimethoxytrityl chloride is a versatile protecting group for primary alcohols, specially useful in oligonucleotide synthesis

Purification Methods

DMT crystallises from cyclohexane/acetyl chloride as the hydrochloride. Dry it over KOH pellets in a desiccator. When dissolved in *C6H6 and air is blown through, HCl is removed. It crystallises from Et2O. [Baeyer & Villiger Chem Ber 36 2788 1903, Smith et al. J Am Chem Soc 84 430 1962, Smith et al. J Am Chem Soc 85 3821 1963.] Ifit has hydrolysed considerably (see OH in IR), then repeat the crystallisation from cyclohexane/acetyl chloride — excess of AcCl is removed in a vacuum over KOH, then recrystallise it from Et2O. [Beilstein 6 IV 1042.]
