A novel Cu(I)-catalyzed intermolecular cyanoarylation of alkenes with diaryliodonium salts as a radical arylating reagent and tetra-butylammonium cyanide as an electrophilic cyanating reagent was established. A broad range of α-alkylated arylacetonitriles were efficiently constructed in good to excellent yields under base- and oxidant-free and mild conditions.

铜（i）催化的烯烃分子间氰基芳基化：便捷地获得α-烷基化的芳基乙腈。

建立了一种新型的Cu（Ⅰ）催化的烯烃间分子氰基氰基化反应，以二芳基碘鎓盐为自由基芳基化试剂，氰化四丁基铵为亲电氰化试剂。在无碱和无氧化剂以及温和的条件下，可以有效地以良好至极好的收率有效地构建了多种α-烷基化的芳基乙腈。
