Pd(II)-NHC catalyst preparation method and application in Suzuki-Miyaura reaction, relates to a catalyst preparation method and application in reaction, the invention discloses Pd(II)-azacyclic carbene (Pd(II) ‑NHC) catalyst preparation method and its application in the Suzuki‑Miyaur reaction. Two kinds of Pd(II)-NHC catalysts in the present invention all use K 2 PdCl 4 as the precursor, and the ligands H 2 L 1 and H 2 L 2 respectively use two (1-imidazolyl) methane and N-(2-chlorophenyl) Acetamide and N-(2-chloro-(2,6-diisopropyl)) acetamide are reacted and condensed to obtain catalysts Pd-(H2L 1 ), Pd-(H2L 2 ) by a step-by-step synthesis method. The two novel catalysts have well-defined structures and are stable to water and air; in the Suzuki‑Miyaura reaction, the reaction conditions are mild, the post-treatment is simple, and the catalytic activity and selectivity are good. |
