We have found that cross-coupling between aryl Grignard reagents and allylic methyl ethers proceeded well in the presence of a catalytic amounts of Fe(acac)3 to afford the corresponding allylic substitution products in good yields. Under the same conditions, allylic trimethylsilyl ethers also reacted with Grignard reagents to give the corresponding cross-coupling products.
我们发现芳基格氏试剂和烯丙基甲基醚之间的交叉偶联在催化量的 Fe(acac)3 存在下进行得很好,以良好的产率提供相应的烯丙基取代产物。在相同条件下,烯丙基三甲基甲硅烷基醚也与格氏试剂反应,得到相应的交叉偶联产物。
