The first ortho‐alkenylation of aromatic amidines with alkynes was realized by earth‐abundant manganese catalysis through C−H activation. A catalytic amount of PhMgBr was found essential for improved efficiency of this transformation. Wide tolerance of functional groups and excellent E/Z selectivity highlighted the current protocol.
