2-(Trimethylsilyl)ethoxymethyl chloride Chemical Properties,Usage,Production

Chemical Properties

Colorless to light yellow liqui

Physical properties

bp 57–59 °C/8 mmHg; d 0.942 g cm?3.

Uses

2-(Chloromethoxy)ethyltrimethylsilane is used in the preparation of SEM [2-(trimethylsilyl)ethoxy]methyl]-ethers. It serves as a phenol protecting group in the synthesis of laterifluorones. Further, it reacts with 1H-imidazole to prepare 1-(2-trimethylsilanyl-ethoxymethyl)-1H-imidazole.

Uses

2-(Trimethylsilyl)ethoxymethyl Chloride is a reagent used in the protection of alcohols, secondary aryl amines, and imidazole, indole, and pyrrole nitrogens;electrophilic formaldehyde equivalent; acyl anion equivalent,used in One-carbon Homologations, Cyclizations etc.

General Description

2-(Trimethylsilyl)ethoxymethyl chloride (SEM-Cl) is a widely used reagent for the preparation protection groups for amines, alcohols, phenols, and carboxy groups. The nitrogen of amides and sulfonamides groups are also protected by using SEM-Cl reagent.

Purification Methods

Dissolve SEMCl in pentane, dry it (MgSO4), evaporate and distil the residual oil in a vacuum. Stabilise it with 10ppm of diisopropylamine. Store it under N2 in a sealed container in a refrigerator. [Lipshutz & Pegram Tetrahedron Lett 21 3343 1980.]
