3-Trimethylsilyl-3-buten-2-one

Physical properties

bp 72 °C/50 mmHg.

Uses

3-Trimethylsilyl-3-buten-2-one is a methyl vinyl ketone homolog useful as a Michael acceptor in annulation reactions, γ,δ-unsaturated ketone formation, Diene Adduct, and Peterson condensations; precursor to a stabilized Diels–Alder diene.

Preparation

3-Trimethylsilyl-3-buten-2-one is prepared by the reaction of (1-bromovinyl) trimethylsilane with acetaldehyde. An alternative synthesis from acrolein has been published.

storage

3-Trimethylsilyl-3-buten-2-one shows no tendency to deteriorate when stored under an argon atmosphere at -20 °C.
