Direct amination of unactivated allylic alcohols with aqueous ammonia was catalyzed by a Pt/phosphine complex to give the corresponding allylamines along with water as the sole by‐product. Under optimized reaction conditions, primary allylamines were obtained as major products with excellent monoallylation selectivity. cod=1,5‐cyclooctadiene.
