Palladium-Catalyzed Carbonylation in the Synthesis of N-Ynonylsulfoximines

Abstract

Palladium-catalyzed carbonylation reactions with Cr(CO)6 as carbonyl source are key for the preparation of N-ynonylsulfoximines from NH-sulfoximines and bromoalkynes. The couplings proceed at room temperature with a wide range of substrate combinations affording the corresponding products in good yields. (Figure presented.).
