A facile and novel protocol for the allylic amination of internal alkynes with amines by using a polymer‐supported triphenylphosphane–palladium complex [PS–TPP–Pd] as a highly active heterogeneous reusable catalyst was developed. The catalyst exhibited remarkable activity and is reusable over five consecutive cycles. The protocol was applicable for a variety of hindered and functionalized aromatic/aliphatic amines and afforded the desired allylic products in good to excellent yield.
