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

Decyanation of geminaldinitriles and α-alkoxycarbonyl substituted nitriles promoted by samarium(II) iodide has been efficiently achieved. This method has advantages over the previously known radical route using tin hydride with respect to applicable substrates and the reaction temperature employed. This decyanation could broaden the synthetic applicability of the nitrile derivatives.

iodoarenes for the synthesis of α-aryl nitriles is described. The NHP ester substrate is derived from cyanoacetic acid, which allows for a modular synthesis of substituted α-aryl nitriles, an important scaffold in the pharmaceutical sciences. The reaction exhibits a broad scope, and many functional groups are compatible under the reaction conditions, including complex highly functionalized medicinal agents
