Chelation-assisted rhodium hydride-catalyzed regioselective H/D exchange in arenes

A series of air stable rhodium(III) hydride complexes are synthesized via cyclometalation of functionalized arenes, and are active catalysts for regioselective H/D exchange in various arenes via chelation-assisted C-H activation in acetone-d6.

A series of air stable ionic rhodium(III) phosphine hydride complexes are synthesized via cyclometalation of functionalized arenes and prove to be active catalysts for regioselective H/D exchange in various arenes via chelation-assisted C-H activation in acetone-d6.
