A novel rhodium-catalyzed H/D exchange of primary, secondary, and tertiary benzylic C−H bonds by means of an η6-coordination strategy is reported. The method, which features high regioselectivity and stereoretention, shows broad functional group tolerance and has been used in late-stage labeling of pharmaceuticals.
