碱性离子液体[bmim]OH能快速、高选择性地催化有机硫试剂与丙烯酸乙烯酯之间的直链加成反应.通过这种方法,合成了12种β-烷基硫取代的丙酸乙烯酯类含硫化合物.进一步调控反应温度和时间可以实现Michael加成和分子内的加成-消除反应的一锅串联成环反应.利用碱性离子液体[bmim]OH选择性促进巯基亲核性的策略,成功地合成了6种七元硫杂环化合物,对产物进行了表征确定.
Alkaline ionic liquid [bmim] OH can catalyze the linear addition reaction between organosulfur agent and vinyl acrylate rapidly and selectively. By this method, 12 kinds of β-alkylsulfide-substituted propionic acid Vinyl esters containing sulfur compounds.Furthermore, the reaction temperature and time can be adjusted to achieve Michael addition and intramolecular addition-elimination reactions in one pot.Meanwhile, the basic ionic liquid [bmim] OH is used to selectively enhance the thiol nucleophilicity Sexual strategy, successfully synthesized six kinds of seven-membered sulfur heterocyclic compounds, the product was characterized to determine.
