用固 液相转移催化法 ,以酞酰亚胺和丙烯腈为原料 ,无水K2 CO3为催化剂 ,经Michael反应合成了 β 酞酰亚胺基丙腈 ,并研究了不同条件下的反应结果。实验表明 ,利用Michael反应在温和条件下可获得较高产率的产物 ,克服了以往用季铵碱作催化剂或用DMF作溶剂的缺点 By using solid-liquid phase transfer catalysis, phthalimide and acrylonitrile as raw materials, anhydrous K2 CO3 as catalyst, β-phthalimidopropionitrile was synthesized by Michael reaction and the reaction results under different conditions were studied. Experiments show that the use of Michael reaction under mild conditions to obtain a higher yield of the product to overcome the previous quaternary ammonium base as a catalyst or DMF as a solvent shortcomings
