Palladium(II)‐Catalyzed N‐Carbonylative Cross‐Coupling Reaction of Sulfoximines with Aryl, Heteroaryl, and Alkenyl Halides Using Tungsten Hexacarbonyl as Carbon Monoxide Source.

Palladium(II)‐catalyzed N‐acylation was demonstrated through the reaction of N−H sulfoximines with a variety of aryl, heteroaryl, and aryl halides using W(CO)6 as a source of carbon monoxide, affording N‐acylated sulfoximines in good to excellent yields. Moreover, alkenyl bromides underwent palladium(II)‐catalyzed N‐acylation reactions with N−H sulfoximines, leading to the formation of N‐cinnamoyl sulfoximines. This method has the advantages of a broad substrate scope, high functional group tolerance, simple operation, and chemoselectivity between chloride and bromide. [ABSTRACT FROM AUTHOR]
