catalyst system and molecular oxygen as a green oxidant, acrylanilides and N‐allylanilines undergo oxidative cascade cyclization to form heterocyclic rings in high yields. This methodology is applicable to acrylanilides of different substitution patterns on olefinic units. Mechanistic studies revealed that cyclization of acrylanilides proceeded through an intramolecular syn‐amidopalladation pathway. The
