Iron(III) p-toluenesulfonate, Fe(OTs)3·6H2O, is an inexpensive, versatile and commercially available catalyst for the allylation of acetals using allyltrimethylsilane to yield homoallyl ethers in moderate to good yields. The one-pot conversion of aldehydes to homoallyl ethers using alkoxysilanes has also been accomplished using Fe(OTs)3·6H2O as a catalyst. The use of mild reaction conditions and a
对甲苯磺酸铁(III)Fe(OTs)3 ·6H 2 O是一种廉价,通用且可商购的催化剂,用于使用烯丙基三甲基硅烷将乙缩醛进行烯丙基化,以中等至良好的产率生成均烯丙基醚。使用Fe(OTs)3 ·6H 2 O作为催化剂,还可以使用烷氧基硅烷将醛单锅转化为均烯丙基醚。使用温和的反应条件和相对无腐蚀性的催化剂使该方法成为合成一系列均烯丙基醚的有吸引力的选择。
