The Synthesis of O-Silyl Ketene Acetals from α-Haloesters

α-Haloesters of the general structure R1R2CXCO2R3 1 have been shown to react with sodium in the presence of a halosilane 2 to yield the corresponding O-silyl ketene acetals 3 (SKAs) according to equation 4.The factor that most influences the yields in these reactions is the concentration of halosilane; if there is a deficiency of halosilane, then acyloin condensation products will detract from the yield of SKAs.The reaction is quite general, and often gives yields in excess of 90percent of the desired SKAs.
