摘要:
We report an innovative palladium-catalyzed hydroaminocarbonylation approach that efficiently converts nitroarenes and terminal alkynes into alpha,(3-unsaturated amides. This method, with broad substrate compatibility, delivers 32% to 87% yields with excellent regioselectivity. Central to the effectiveness of this reaction are the bipyridine ligand and salicylic acid, which play pivotal roles in optimizing both selectivity and product yield. Mechanistic experiments revealed that arylamine serves as a critical intermediate in the overall reaction, highlighting a unique pathway in the catalytic cycle. In contrast to conventional procedures, this protocol employs diverse nitroarenes and Mo(CO)6 as direct nitrogen and solid carbonyl sources, streamlining the process and enhancing safety by reducing the reliance on hazardous CO gas.
