A rhodium(III)-catalyzed direct cross-coupling reaction of indolines with maleimides via C–H bond activation was developed. This protocol displays good functional group tolerance, which offers a novel approach to access C7 modified indoline derivatives including maleimide analogues.

A rhodium-catalyzeddirect C–H sulfonamidation and amidation of C-7 position of indolines by simple and commercially available arylsulfonamides and trifluoroacetamide has been developed, affording a series of N-arylsulfonamides and N-aryltrifluoroacetamides in moderate to excellent yields, respectively. Notably, this catalytic system is highly convenient on mmol scale.
A manganese biopolymer-supported catalyst is reported for hydrogen/deuteriumexchange in anilines, phenols, heterocycles, and electron-rich arenes. Notably, taking advantage of deuterium oxide as easy-to-handle isotope source, deuterated compounds are obtained in high yields in a practical manner.
