Abstract
Abstract A Rh(III)‐catalyzed ortho C−H functionalization of N‐ nitrosoanilines with α ‐sulfonylcarbenes had been developed. The reaction was carried out under mild conditions and the products were obtained with good to excellent yields. The diverse transformations of the products to ortho ‐functionalized anilines and nitrogen heterocycles were achieved. Furthermore, a cascade reaction of N‐ nitrosoanilines and α ‐sulfonyl‐ α ‐diazo‐ketones provided 3‐sulfonyl‐indoles efficiently. magnified image
