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.
