Mild and tolerant: A novel PdII‐catalyzed CH bond arylation with aryl‐BF3K salts transforms various electron‐deficient arenes under mild reaction conditions. Benzaldehydes are functionalized in the ortho position using a temporary imine directing group that controls the cyclopalladation. A broad range of benzaldimines are compatible with this process (see scheme).
