    Sevelamer as an efficient and reusable heterogeneous catalyst for the Knoevenagel reaction in water
    摘要:
    A catalyst system of Sevelamer, a phosphate-binding drug, has been prepared and used in the Knoevenagel reaction of aromatic aldehydes in water to produce substituted electrophilic alkenes. The products were obtained in excellent yields. Several novel, related catalytic systems showed promising catalytic properties for aromatic and heterocyclic aldehydes. The Sevelamer catalyst can be recovered using simple filtration and reused numerous times (up to 15 times) in the aqueous Knoevenagel reaction without any significant lowering of activity.

    Abstract:

    This research work presents the use of base-modified Tunisian Smectite as catalysts for the condensation of Knoevenagel. The prepared clay-catalysts were characterized via FTIR and XRD studies. A series of condensation reactions based on ultrasonic irradiation of various types of active methylene compounds and a variety of aryl aldehydes have shown the high efficacy of prepared catalysts. The stability and catalytic performance of the clay-catalysts were excellent since they could be reused four times without considerable loss in catalytic activity
