摘　　要：芳香族有机碲氧化物有效地催化β-苯砜基乙酸甲酯、乙酯、苯乙酮及丙酮与醛的 Knoevenagel反应 ,合成α,β-不饱和酯基或羰基苯砜化合物 ,并有较好的产率 ,同时探讨了影响该反应的主要因素。Some α,β unsaturated ester or carbonyl phenylsulfones have been synthesized by condensation of the methyl β phenylsulfonyl acetate,ethyl β phenylsulfonyl acetate,β phenylsulfonyl acetophenone and β phenylsulfonyl acetone with aldehydes in the presence of aryltelluoxides as catalyst. Good yields were obtained. The factors that affected the reaction were discussed.
