Furfural activated again: a Ru‐catalyzed arylation and alkenylation of furfural imines with aryl‐ or alkenyl‐boronates, involving a directed C‐H activation occurring at C3 of the furan ring, was developed. It was revealed that an electron‐rich aromatic imine, such as a p‐dimethylaminophenyl‐imine, enables the coupling with good yields. After the coupling, a smooth hydrolytic removal of the imine directing‐group
