Dimethylphenylsilane Chemical Properties, Uses, Production

Synthesis

Synthetic Route of Dimethylphenylsilane

A solution of dichlorodimethylsilane (5 g, 38.5 mmol) in dry ether (20 mL) was added dropwise at 0 °C under argon atmosphere to a stirred solution of magnesium phenyl bromide (prepared from bromobenzene) (6.55 g, 42 mmol) and magnesium (1.0 g, 42 mol) in dry diethyl ether (30 mL). The solution was then refluxed for 24 hours and cooled to room temperature. Pentane (40 mL) was added and the solution was filtered. The solvent was evaporated under vacuum at a temperature below 40 °C, and the product was distilled under reduced pressure to give Dimethylphenylsilane.

Chemical Properties

Clear colorless liquid

Physical properties

bp 157 °C/744 mmHg; d 0.889 g cm3.

Uses

Diastereoselective Reduction of Carbonyl Compounds.
Hydrosilylation. With a transition metal catalyst, the hydrosilane adds to carbon–carbon double or triple bonds to give alkylsilanes or alkenylsilanes.
Hydrosilylating reagent; reductant in combination with acid or F).

Uses

Dimethylphenylsilane is a reagent for enol ether synthesis. It acts as a catalyst. Also used as a precursor in Optical Emission Spectroscopy of Plasma Deposition Processes. It can react with vinylbenzene to produce (b-Phenyl-ethyl)-dimethylphenyl-silan.

Application

Used to reduce α-amino ketones to aminoethanols withhigh stereoselectivity. Used in the fluoride ion-catalyzedreduction of aldehydes and ketones, and α-substitutedalkanones to threo products. Erythro reduction of α-substituted alkanones to diols and aminoethanols. Together with CuCl reduces aryl ketones, but not dialkylketones. Used in the silylformylation of acetylenes.Excellent reducing agent for the reduction of enones tosaturated ketones. Shows better selectivity than LAH inthe reduction of oximes to alkoxyamines.
