摘要

Abstract This paper describes the first use of polystyrene-supported poly (amidoamine)(PAMAM) dendrimers as heterogeneous basic organocatalysts for carbon– carbon bond formation. Polystyrene-supported PAMAM dendrimers of first, second and third generations have been used as reusable base catalysts in Knoevenagel condensations of carbonyl compounds with active methylene compounds. The reactions proceed in short ...
