A New Solvent-Free Reaction for the Preparation of Alkoxysilane from Cyclic Ethers, Alcohols, or Carbonyl Compounds

The 1,1,3,3-tetramethyldisiloxane/Pd/C system is reported here as a new method to accomplish the ring-opening of ethers and epoxides to give protected alcohols. The approach can also be used for the protection of primary or secondary alcohols and for the reduction of aldehydes and ketones to obtain alkoxysilanes.
