| titleOfInvention | 1, 3-conjugated diene compound, preparation method and application thereof |
| abstract | The invention discloses a 1, 3-conjugated diene compound, a preparation method and application thereof. The present invention provides a method for preparing a 1, 3-conjugated diene compound, comprising the steps of: in an organic solvent, in the presence of a palladium catalyst, a phosphine ligand and an alkaline reagent, carrying out 1,4-Pd migration/suzuki coupling reaction shown in the specification on an aromatic halide containing a structural fragment shown in a formula I and an alkenyl boron compound containing a structural fragment shown in a formula II to obtain a compound containing a structural fragment of the 1, 3-conjugated diene shown in a formula III. The preparation method has high stereoselectivity and product configurationThe unity; the substrate universality is good, and the electron-deficient olefin, the electron-rich olefin and the polysubstituted olefin can be compatible; and has the characteristics of mild reaction conditions, wide functional group compatibility and the like. The 1, 3-butadiene compound provided by the invention can realize a higher aggregation-induced emission effect. |
