Abstract:
Since 1987, stoichiometric cyclomanganation of ketones and subsequent reactions with olefins in the presence of either palladium salts or trimethylamine N ‐oxide (Me 3 N + O − ) have been reported, but the catalytic versions remain untouched so far. Herein, the first manganese‐catalyzed redox‐neutral C−H olefination of ketones with unactivated alkenes is described, and shows a distinct reactivity with its parent stoichimetric reactions. Remarkably, mechanistic experiments and DFT calculations uncovers a unique concerted bis‐metalation deprotonation (CBMD) mechanism of the Mn‐Zn‐enabled C−H bond activation.
