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).
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.
