New disiloxane based on N-acetylvaline: synthesis and structure

Silylmethylation of N-acetylvaline with the ClCH2SiMe2Cl—(Me3Si)2NH system gave the previously unknown 2-silamorpholin-6-one derivative, whose hydrolysis in aqueous ethanol produced bis-acetylvaline-containing disiloxane. The X-ray diffraction study and quantum chemical calculations demonstrated that both silicon atoms in the final product are four-coordinated.
