DIMETHYLSILYLDIETHYLAMINE Chemical Properties,Usage,Production

Physical properties

bp 112°C/760 mmHg; n20 D 1.4087; d20 4 0.7505 g cm?3.

Uses

N,N-Diethylaminodimethylsilane is a useful reagent for the conversion of hydroxy groups of allyl or homoallyl alcohols into hydrodimethylsilyl ethers for use in intramolecular hydrosilation reactions. In some cases, N,N-diethylaminodimethylsilane gives superior results compared to the more commonly employed 1,1,3,3-tetramethyldisilazane (eq 1).

Preparation

by treatment of commercially available chlorodimethylsilane (ClMe2SiH) and diethylamine in the presence of triethylamine in ether, followed by filtration and distillation.
