The development of the reactivity on carbene complexes would lead to the creation of novel synthetic strategies. We discovered herein the Pd-catalyzed desulfurative amide formation involved Suzuki-Miyaura coupling reaction, notably the Pd complex was generated in situ from thioureas, Ag salt and Pd catalyst. Silver salt was essential for the construction of this type of carbenes from available and stable thioureas and well participated in the catalytic cycle. We report a method for the synthesis of arylamides from arylboronic acids, which greatly enriched the application of thiourea chemistry and expanded the application of the Suzuki-Miyaura coupling.

Abstract Aryl (pseudo)halide-based (C-X) carbonylation reactions have been extensively studied during the past few decades. From both academic and synthetic points of view, the carbonylative transformation of N-X bonds represents an interesting and attractive area of investigation. In light of this, the first carbonylative cross-coupling between N-chloroamines and organoboronic acids has been developed. This new type of aminocarbonylation proceeds at mild temperatures (45-55 °C) with 2 mol % Pd/C (10 wt %) as the ligand-free catalyst. Not only arylboronic acids, but also alkenyl- and alkylboronic acids can be applied as the substrates and bromide and iodide substituents in the substrates are well tolerated. Initial mechanistic investigations have also been performed. Umpolung aminocarbonylation: The first palladium-catalyzed carbonylative cross-coupling between N-chloroamines and organoboronic acids has been realized. Various amides were isolated in moderate to excellent yields from reactions under mild temperatures with ligand-free Pd/C as the catalyst. Not only arylboronic acids, but also alkenyl- and alkylboronic acids are applied as the substrates and bromide and iodide substituents in the substrates are well tolerated.
