Supported N-alkylimidazole-decorated dendrons as heterogeneous catalysts for the Baylis-Hillman reaction

The Baylis-Hillman reaction between methyl vinyl ketone and aromatic aldehydes, catalyzed by N-alkylated imidazoles immobilized on polystyrene via dipolar cycloaddition, esterification or nucleophilic substitution, exhibits a remarkable positive dendritic effect.
