A polystyrene-supported zinc bromide-ethylenediamine complex was shown to be useful as a recyclable heterogeneous catalyst for the rapid and efficient synthesis of α,β-acetylenic ketones in good-to-excellent yields by cross-coupling of acid chlorides with terminal alkynes. The catalyst is easily prepared, stable, reusable, and efficient under the reaction conditions. heterogeneous catalysis - cross-coupling
