The Uses of Dimethylphenylsilane

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.

The Uses of Dimethylphenylsilane

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?).

What are the applications of 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.
