Transition‐metal‐free synthesis of α‐arylesters and nitriles using arylboronicacids with α‐aminoesters and α‐aminoacetonitriles, respectively, as the starting materials has been developed. The reaction represents a rare case of converting C(sp3)N bonds into C(sp3)C(sp2) bonds. The reaction conditions are mild, demonstrate good functional‐group tolerance, and can be scaled up.

conditions, affording α‐(hetero)arylacetonitriles via one‐pot decarboxylation. Additionally, the CuBr/oxalic diamide catalyzed coupling of (hetero)aryl bromides with α‐alkyl‐substituted ethyl cyanoacetates proceeds smoothly at 60 °C, leading to the formation of α‐alkyl (hetero)arylacetonitriles after decarboxylation. The method features a general substrate scope and is compatible with various functionalities
