description The invention discloses a preparation method of Pd(II)-NHC catalysts and applications of the Pd(II)-NHC catalysts in Suzuki-Miyaura reactions, relates to a catalyst preparation method and applicationsof the catalysts in reactions, and discloses a preparation method of Pd(II)-N-heterocyclic carbene (Pd(II)-NHC) catalysts and applications of the Pd(II)-N-heterocyclic carbene (Pd(II)-NHC) catalystsin Suzuki-Miyaur reactions. According to the two Pd(II)-NHC catalysts of the invention, K2PdCl4 is used as a precursor, ligands H2L1 and H2L2 are respectively obtained by carrying out a condensation reaction on bis(1-imidazolyl)methane and N-(2-chlorphenyl)acetamide and on bis(1-imidazolyl)methane and N-(2-chloro-(2,6-diisopropyl)acetamide, and the catalysts Pd-(H2L1) and Pd-(H2L2) are prepared through a step-by-step synthesis method. The two novel catalysts are clear in structure and stable to water and air; and in a Suzuki-Miyaura reaction, the reaction conditions are mild, the post-treatment is simple, and the catal
