Sustainable Manganese‐Catalyzed C−H Activation/Hydroarylation of Imines

Expedient C−H additions of heteroarenes onto aldimines were realized by a sustainable manganese catalysis manifold within a removable directing group strategy. The C−H activation features most user‐friendly reaction conditions, excellent chemo‐ and position‐selectivity as well as ample substrate sco...

Description
Summary:Expedient C−H additions of heteroarenes onto aldimines were realized by a sustainable manganese catalysis manifold within a removable directing group strategy. The C−H activation features most user‐friendly reaction conditions, excellent chemo‐ and position‐selectivity as well as ample substrate scope. Detailed experimental mechanistic studies suggest an organometallic C−H manganesation mode of action. SusMn: Manganese catalysis enabled the step‐economical C−H activation/hydroarylations of aldimines with ample scope by an organometallic C−H activation regime.
