γ,γ-Dialkoxyallylic zirconium species can be easily prepared from the reaction of triethyl orthoacrylate with zirconocene equivalent (zirconocene-butene complex). This species reacts with aldehydes as an α,β-unsaturated acyl anion equivalent to give the 1-substituted-2,2-diethoxy-3-buten-1-ol derivatives.
γ,γ-二烷氧基烯丙基锆物质可以通过原丙烯酸三乙酯与锆茂当量(锆茂-丁烯络合物)的反应容易地制备。该物质与醛反应,成为α,β-不饱和酰基阴离子当量,得到1-取代的2,2-二乙氧基-3-丁烯-1-醇衍生物。
