Hydrogen bond donating capacity of hexafluoroisopropanol was shown to be responsible for both the formation of its stoichiometric complexes with aldehydes and acetals and subsequent facilitation of their reactions with allylsilanes.

transfer to gem-disubstituted alkenes to form silacyclopropanes, we discovered an unprecedented reaction of homoallylic ethers. When silylene transfer was performed at room temperature or above, two di-tert-butylsilylene units were incorporated into the molecule, and complete rearrangement of the carbon backbone occurred. This report describes the scope of this unique reaction as well as the mechanistic
