Tolerant: By using Pd(OAc)2/PCy3 as a catalyst, both electron‐rich aromatic heterocycles and electron‐deficient fluorobenzenes undergo the dehydrogenative cross‐coupling with (hetero)aryl ethyl ketones in good yields. A broad range of functional groups is tolerated, thus providing a general method for the facile syntheses of chalcones or heterocyclic chalcone analogues. Furthermore, dialkyl ketones can also
