In contrast to almost all of the known examples of Heck arylation of unsaturated alcohols, which yield predominately beta-arylated products, arylation under the Pd-DPPP catalysis in ionic liquid leads preferentially to aryl substitution at the alpha carbon, providing an easy pathway to this valuable class of olefins.
与几乎所有已知的不饱和醇的Heck芳基化反应例子不同，那些反应主要生成β-芳基化产物，而在离子液体中Pd-DPPP催化下的芳基化反应优先导致α-碳上的芳基取代，为这类有价值的烯烃提供了一条简便途径。
