Abstract

A Rh-catalyzed redox-neutral annulation of primary benzamides with diazo compounds provides isoquinolinones. This efficient and economic procedure exhibited good functional group tolerability, scalability, and regioselectivity, obviating the need for oxidants, and only environmentally benign N2 and H2O were released.
