[reaction: see text] Iron(III) chloride-catalyzed effective allylation reactions of acetals with allyltrimethylsilane proceeded smoothly in high to excellent yields. In addition, this method could be applied to the one-pot synthesis of homoallyl benzyl ethers by a combination of dibenzyl acetalization of aldehydes and consecutive allylation of dibenzyl acetals.
[反应：见正文] 在氯化铁（III）催化下，缩醛与烯丙基三甲基硅烷顺利进行有效的烯丙基化反应，产率高至优异。此外，通过醛的二苄基缩醛化和二苄基缩醛的连续烯丙基化相结合，该方法可应用于高烯丙基苄基醚的一锅法合成。
