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

An unusual oxidative coupling reaction of isocyanide and toluene derivatives using tetrabutylammonium iodide (TBAI) as a catalyst is disclosed. The experimental results and mechanistic study show that the isocyano group acts formally as an N1 synthon during the transformation, thus expanding the reactivity profile of isocyanide.
A new and efficient method for the synthesis of amides via palladium-catalyzed C−C coupling of arylhalides with isocyanides is reported, by which a series of amides were formed from readily available starting materials under mild conditions. This transformation could extend its use to the synthesis of natural products and significant pharmaceuticals.
Iodobenzene derivatives possessing various substituents (amino, hydroxy, tert-butyl, methyl, isopropyl, phenyl, fluoro, chloro, methoxycarbonyl, acetyl, trifluoromethyl, nitro) in the para position were aminocarbonylated using tert-butylamine and n-butylamine as N-nucleophiles. A palladium(0) catalyst formed in situ from palladium(II) acetate and triphenylphosphine was used. Carboxamide and ketocarboxamide
