Suzuki–Miyaura cross-coupling of N-acylsuccinimides as versatile acyl-transfer reagents via selective amide N–C bond cleavage is reported. The method is user-friendly since it employs commercially-available, air-stable reagents and catalysts. The cross-coupling is enabled by half-twist of the amide bond in N-acylsuccinimides. These highlyeffective, crystalline acyl-transfer reagents present major advantages
An acylative Suzuki coupling of activated amides with aryl boronic acids has been reported via palladium-catalyzed CN bond cleavage. This protocol demonstrate amides can be activated by an atom-economic and cheap succinimide, which can be efficiently utilized to synthesize broad array of diaryl ketones in moderate to good yields.
