A novel product‐derived bimetallic palladium complex catalyzes a sulfonylazide‐transfer reaction with the σ‐donor/π‐acceptor ligand CO, and is advantageous given its broad substrate scope, high efficiency, and mild reaction conditions (atmospheric pressure of CO at room temperature). This methodology provides a new approach to sulfonylureas, which are present in both pharmaceuticals and agrochemicals
源自产物的新型双金属钯络合物可催化与σ-供体/π-受体配体CO进行磺酰叠氮化物转移反应,并且由于其广泛的底物范围,高效率和温和的反应条件(CO在室温下为大气压)而具有优势)。这种方法为药物和农用化学品中都存在的磺酰脲类提供了一种新方法。以克为单位的格列本脲的合成进一步揭示了该方法的实用性。从机理上讲,衍生自磺酰脲产物的桥接双金属钯物质的生成被公开为该催化循环的关键步骤。
