Water-Induced Diastereomeric Isomerization of Novel Disiloxane-1,3-diols Separated Manually

Diastereomeric disiloxane-1,3-diols, 1, with two asymmetric silicon centers and intramolecular coordination arms were synthesized and separated manually. They show distinguishing structural features such as a linear or bent Si−O−Si skeleton, a short Si−O bond length, and strong intramolecular hydrog...

Summary:Diastereomeric disiloxane-1,3-diols, 1, with two asymmetric silicon centers and intramolecular coordination arms were synthesized and separated manually. They show distinguishing structural features such as a linear or bent Si−O−Si skeleton, a short Si−O bond length, and strong intramolecular hydrogen bonding. A trace of water induced the diastreomeric isomerization of 1 under noncatalytic conditions, while the anhydrous disiloxane-1,3-diols were stereochemically stable.
