Herein, we developed an operational simple, practical, and selective Ni-catalyzed synthesis of secondary amides. Application of renewable alcohols, earth-abundant and nonprecious nickel catalyst facilitates the transformations, releasing water as byproduct. The catalytic system is tolerant to a variety of functional groups including nitrile, allylic ether, and alkene and could be extended to the synthesis

same boat: Tandem rearrangement/N‐alkylation reactions in the presence of a Ru/Ir dual‐catalyst system affords the desired N‐alkylated amines in good‐to‐excellent yields with no intermediate amides or over‐alkylated N,N‐dialkylated amides. This environmentally friendly tandem reaction employs readily available starting materials, affords excellent selectivities for the N‐alkylated amides, and shows
