AgOTf is an effective catalyst for intermolecular allylation of aromatic and heteroaromatic compounds with allylic alcohols affording allylated arenes in up to 99% yields. Heterogeneous allylation of arenes catalyzed by Ag3PW12O40 gave comparable product yields to those obtained by AgOTf. Ag3PW12O40 could be reused five times with slightly decreased activity.
AgOTf 是芳香族和杂芳香族化合物与烯丙基醇进行分子间烯丙基化反应的有效催化剂,可生成烯丙基化的炔类化合物,收率高达 99%。Ag3PW12O40 催化的炔烃异相烯丙基化的产率与 AgOTf 催化的产率相当。Ag3PW12O40 可重复使用五次,但活性略有降低。
