α-Haloenolates have been prepared by halogen—metal or hydrogen—metal interchange. Rearrangement of β-oxido carbenoids offers another useful route, whereas β-alkoxycarbenoids decompose via α- or β-elimination. CuI promotes the preparation of α-halomagnesium enolates. These organometallics undergo useful reactions as nucleophiles, but can also behave as electrophiles. 相似文献
