Ir(III)-Catalyzed Carbenoid Functionalization of Benzamides: Synthesis of N‑Methoxy­isoquinoline­diones and N‑Methoxy­isoquinolinones

A mild and efficient Ir­(III)-catalyzed C–H carbenoid functionalization strategy has been developed to access N-methoxyiso­quinolinediones and N-methoxy­isoquinolinones. The reaction proceeds efficiently in high yield at room temperature over a broad range of substrates without requirement of any additional oxidants or a base.
