Base Catalyzed Eliminations of Trimethylsilanol

Because of the large number of publications in this field, this chapter wiU be limited to giving an idea of developments in this area. Because the Peterson reaction can be viewed as a special case of base-catalyzed reaction, this reaction will be discussed in Section 10.2 after general base-catalyzed eliminations of trimethylsilanol 

On treatment of the silylated dichloromethyl alcohols 1585 with butyUithium, lithium trimethylsilanolate, MesSiOLi, 98 is ehminated and the 1,1-dichloroolefins 1586 are formed in 40-82% yields [5, 6]. Likewise, treatment of sulfoxide 1587 at -30 °C with excess LDA results in ehmination of trimethylsilanol 4 to afford nearly 

Silylated primary amines such as N-silylated aniline 1599 are transformed by sodium methoxide into silylated methanol and amine salts such as 1600, which are
