A practical and user‐friendly strategy for the chain‐end reduction of halogen terminated polymers that employs hydrogen gas and heterogeneous catalysis (palladium on carbon) is reported. Quantitative dehalogenation of a wide variety of monomer families (polystyrenes, polyacrylates, and polymethacrylates) with either chlorine or bromine chain‐ends is observed. The utility of this chain‐end reduction is further highlighted by mild reaction conditions, simple purification, and compatibility with a wide range of solvents.
