Polystyrene-supported Palladium(Ⅱ) Ethylenediamine Complex:A Recyclable Catalyst for the Syntheses of 2-Benzyl-imidazo[2

The polymer-supported palladium(Ⅱ) ethylenediamine complex was used as a catalyst for the heterocyclization during Sonogashira reaction between a substituted phenyl iodide and 2-amino-3-(2-propynyl)-1,3-benzothiazolium bromide, which could readily be recovered from the reaction medium by a simple filtration, and reused without a significant loss in its activity.
