We achieved chemoselective synthesis of α-alkylated arylacetonitriles and acetamides by combining Ir complex-catalysed direct coupling of alcohols and nitriles by a simple adjustment of the base. Methanol and ethanol performed well as the alkylating reagents. This method of acetonitrile alkylation provided a novel approach for carbon chain extension.
我们通过简单的碱调节,结合 Ir 络合物催化的醇和腈的直接偶联,实现了 α-烷基化芳基乙腈和乙酰胺的化学选择性合成。甲醇和乙醇作为烷基化试剂表现良好。这种乙腈烷基化方法为碳链延长提供了一种新方法。

A novel Cu(I)-catalyzedintermolecular 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.
