Abstract
In the presence of strong acids, l-hydroxyalkyl-tris(trimethylsilyl)si lanes (la-c) undergo a rearrangement under formation of bis(trimethyls ilyl)-1-trimethylsilylalkylsilanols (4a-c). The conversion is interpre ted as proceeding through a silylium ion intermediate, which can be tr apped with methanol or hydrofluoric acid to give the methoxysilane 5 o r the fluorosilane 6 respectively.
