| titleOfInvention | Ruthenium olefin metathesis catalyst with ortho-position steric hindrance structure and preparation method and application thereof |
| abstract | The invention discloses a ruthenium olefin metathesis catalyst with an ortho-position steric hindrance structure, and a preparation method and application thereof. The catalyst has the following structural general formula And comprises the following preparation method: (1) reduction of Zn (OAc) 2 ยท2H 2 Dissolving O and the compound (I) in an isopropanol solvent, adding ethylenediamine, filtering the precipitated solid after reaction, washing with methanol and chloroform, and drying in vacuum to obtain a compound (II); (2) under nitrogen, Grubbs-Hoveyda II and compound (II) are addedIn dry tetrahydrofuran solvent, after reaction in N 2 Then the solvent is centrifuged, the solution is collected and drained to solid, and the solid is washed by anhydrous ether and dried to obtain the ruthenium olefin metathesis catalyst compound (III). The method has simple steps and mild reaction conditions, can obtain the cis-structure product with a specific configuration by reacting at room temperature, and has wide application prospect. |
