Polystyrene-IIDQ is a polymer-supported coupling reagent that couples carboxylic acids to amines in good yields and high purity without the requirement of a pre-activation step. Importantly the order of addition of the amine, acid or coupling agent makes no difference to the efficiency of the coupling reaction and the reagent can be readily regenerated.
