Oxidation of α-hydroxysilanes by lead tetraacetate
Paredes, Maria Dolores,Alonso, Ricardo
, p. 3973 - 3976 (1999)
The effect of α-silyl substitution on the oxidation of alcohols by lead tetraacetate has been evaluated. Under typical conditions for converting alcohols to cyclic ethers, α-hydroxysilanes are instead efficiently transformed into mixed acetyl-silyl acetals.
