An efficient, mild and practical approach for the synthesis of amides from nitriles and peroxides is reported in the presence of boron trifluoride ethereate. In this protocol, we utilized peroxides as C1 synthons for the amidationreaction. Also, we successfully prepared boron‐containing β‐ketoamides in a one‐pot assembly from β‐ketonitriles. A variety of functional groups were tolerated in moderate

chloride as a catalyst and chlorotrimethylsilane as an additive. The highly electrophilic and oxophilic tungsten catalyst enables the selective scission of a C–N bond of tertiary alkyl amides to effect transamidation of a myriad of structurally and electronically diverse tertiary alkyl amides and amines. Mechanistic study implies that the synergistic effect of the catalyst and the additive could pronouncedly
iodides with isocyanides to afford alkyl amide, which proceeds via the selective monomigratory insertion of isocyanides with alkyl iodides, subsequent β-hydride elimination, and hydrolysis process. The reaction features wide functional group tolerance under mild conditions. Additionally, the selective, one-pot hydrolysis of reaction mixture under acid conditions allows for expedient synthesis of the corresponding
