| titleOfInvention | Method for synthesizing indole derivatives through magnetic mesoporous polymeric ionic liquid supported catalysis |
| abstract | The invention discloses a preparation method of a magnetic mesoporous polymerization ionic liquid catalyst, which comprises the following steps: 1) dissolving equimolar amounts of 2-bromoethyl acrylate and triethylene diamine in a methanol solution, heating and refluxing for reaction for a certain time at 50-60 ℃ under the protection of vacuum nitrogen, and carrying out reduced pressure concentration and vacuum drying to obtain a light yellow viscous ionic liquid; 2) mixing the ionic liquid obtained in the step 1) with terminal alkene modified Fe 3 O 4 Dissolving divinylbenzene and azodiisobutyronitrile in methanol, heating and refluxing at 60-80 deg.c in vacuum until the reaction is completed, and vacuum drying to obtain the final catalyst. The invention also discloses the catalyst and application thereof in synthesizing indole derivatives and seven-element fused indole. The method has the advantages of high yield, simple operation, simple catalyst recovery, good reusability of a catalytic reaction system, mild reaction conditions and good green industrial prospect. |
