对硝基苯磺酰甲基苯及其衍生物与甲基丙烯酸酯的加成重排羰基化反应

Preparation of γ-Carbonylesters from Michael Addition of P-nitrophenylsulphonylmethylbenzene and its Derivatives with Methylacrylate

在固 液相转移催化剂作用下 ,对硝基苯磺酰甲基苯及其衍生物与甲基丙烯酸酯反应 ,得到连续Michael加成重排羰基化产物 .产物的结构特征都已通过质谱 (MS)、红外光谱 (IR)、1HNMR谱和元素分析得到表征 .

P-nitrophenylsulphonylmethylbenzene and its derivatives reacted with methylacrylate under solid-liquid phase-transfer catalysis to give Michael addition products, which were followed by rearrangement to give γ-carbonylesters. The final products were identified by MS, IR,~1HNMR and elemental analysis. The possible mechanism was briefly discussed.
