Anhydrous lithium iodide in ether, tetrahydrofuran, or benzene is an effective reagent for the formation of αβ-unsaturated ketones by condensation of alkyl ketones with enolisable and non-enolisable aldehydes; in the presence of trimethylchlorosilane–triethylamine enone formation is suppressed and high yields of 1,3-hydroxy-ketones are obtained as their trimethylsilyl ether derivatives.
在醚,四氢呋喃或苯中的无水碘化锂是一种有效的试剂,可通过烷基酮与可烯化和不可烯化的醛缩合来形成αβ-不饱和酮。在三甲基氯硅烷-三乙胺的存在下,烯酮的形成得到抑制,并以其三甲基甲硅烷基醚衍生物的形式获得了高产率的1,3-羟基酮。
