Rhodium(III)‐Catalyzed Aldehyde C−H Activation and Functionalization with Dioxazolones: An Entry to Imide Synthesis

A rhodium(III)-based catalytic system has been used to develop a C−H bond activation of benzaldehyde derivatives and subsequent functionalization with dioxazolones in order afford imides. The importance the nature directing group perform selectively aldehydic highlighted. scope investigation showed that this transformation could be applied various many as well an acrolein derivative. Derivatization reactions imide products demonstrated synthetic utility rhodium-catalyzed amidation.
