ACYLOIN CONDENSATION PDF

A useful relative of the acyloin condensation is the McMurry olefination reaction. In this reaction, ketones or aldehydes are treated with Ti(0) (TiCl3 + LiAlH4;. workup.1–3 This reaction is called Acyloin condensation, named after the prod- This modification has become the standard procedure for the acyloin ester.

The reaction works best when the ketone functional groups have no adjacent enolizable protons, as this allows aldol condensation to condenwation. The process is a 4-electron reduction see details below. Organic reaction topic Organic reactions are chemical reactions involving organic compounds.
