RhIII-Catalyzed Hydroacylation Reactions between N- Sulfonyl 2-Aminobenzaldehydes and Olefins

Metal-catalyzed hydroacylation of olefins represents an important atom-economic synthetic process in CH activation. For the first time highly efficient (RhCp)-Cp-III*-catalyzed hydroacylation was realized in the coupling of N-sulfonyl 2-aminobenzaldehydes with both conjugated and aliphatic olefins, leading to the synthesis of various aryl ketones. Occasionally, oxidative coupling occurred when a silver(I) oxidant was used.
