Dimethylphenylsilane Chemical Properties,Usage,Production

Chemical Properties

Clear colorless liquid

Physical properties

bp 157 °C/744 mmHg; d 0.889 g cm?3.

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.
