The Uses of DIMETHYLSILYLDIETHYLAMINE

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). Reactions of N,N-Diethylaminodimethylsilane

What are the applications of Application

N,N-Diethyl-1,1-dimethylsilylamine is a silylating agent.

Preparation

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