The reaction of allylsilanes with α,β-unsaturated acetals in the presence of titanium tetrachloride afforded diallylated compounds, while monoallylated compounds were obtained selectively by the reaction promoted by aluminum trichloride or boron trifluoride–ether complex.
在四氯化钛存在下,烯丙基硅烷与 α,β-不饱和缩醛反应得到二烯丙基化合物,而单烯丙基化合物通过三氯化铝或三氟化硼-醚络合物促进的反应选择性地获得。
