A method for catalytic intermolecular allylic C−H amination of trans‐disubstituted olefins is reported. The reaction is efficient for a range of common nitrogen nucleophiles bearing one electron‐withdrawing group, and proceeds under mild reaction conditions. Good levels of regioselectivity are observed for a wide range of electronically diverse trans‐β‐alkyl styrene substrates.
