摘要：
Polystyrene-supported DABCO was employed for the first time as a recyclable heterogeneous basic catalyst for one-pot synthesis of beta-phosphonomalonates via tandem Knoevenagel-phospha-Michael reaction at room temperature. The reaction conditions are mild and the method is operationally simple. The catalyst could be easily separated from the reaction mixture by filtration and recycled six times without activity loss.
