Aromatic enamines: para-Vinylanilines were identified as unique nucleophiles, closely resembling enamines, to undergo C[BOND]C coupling with aldehydes catalyzed by a simple primary–tertiary diamine/Brønsted acid. The resulting bis(allylic) adducts, which have potential as functional materials, were obtained in high yields under rather mild conditions (see scheme).
