摘　　要：在无溶剂,无催化剂,超声辐射下芳香醛与丙二腈发生knoevenagel缩合反应,合成了一系列苄叉基化合物,通过熔点的测定,红外光谱、核磁共振及元素分析对产物的结构进行了表征。结果表明,该方法不但化学选择性好,而且产物易处理,对环境污染小,符合绿色化学的要求。A series of styrene compounds were synthesized in the reaction of different aromatic aldehydes with malononitrile under ultrasound irradiation and solvent-free conditions without catalysis. Products were characterized by mp, IR, ^1H NMR, ^13 CNMR and elemental analysis. As a result, the method has not only execllent chemical selectivity, high yicld, hut aslo the manageability of products ,less pollution. It is in accordance with the requirement of green chemistry.
