What is tert-Butyldimethylsilane?
The Uses of tert-Butyldimethylsilane
Tert-Butyldimethylsilane (t-BuMe2SiH) is widely used for the protection of hydroxy groups in sugars. Its oxidation product, tert-butyldimethylsilyl hydroperoxide (t-BuMe2SiOOH), is used for preparing luminiscent sources and prostanoids, specifically clavulons[1].
