The manganese(I) complex bearing a bidentate hydrazone ligand efficiently catalyzes the α-alkylations of nitrile using primary alcohols as alkylating agents. α-Functionalized nitriles were selectively obtained in good to excellent yields. The reaction is environmentally benign, producing water as the sole byproduct. Both benzylic and aliphatic alcohols could be used and functional groups were tolerated

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

The α-alkylation of nitriles with primary alcohols to selectively synthesize nitriles by a well-defined molecular homogeneous cobalt catalyst is presented. Thirty-two examples with up to 95% yield are reported. Remarkably, this transformation is environmentally friendly and atom economical with water as the only byproduct.
