Zusammenfassung:The invention relates to a preparation method of an N-heterocyclic carbene zinc complex catalytic material. The method comprises the following steps: (1) preparing 2-(2-bromoethoxy) pyrene; (2) preparing bis (benzimidazole) butane; (3) preparing bis-benzimidazole pyrene salt: mixing 2-(2-bromoethoxy) pyrene, bis-benzimidazole butane and acetonitrile, performing reflux reaction, and performing rotary evaporation, thereby obtaining the bis-benzimidazole pyrene salt. (4) preparing a free N-heterocyclic carbene compound: under the protection of nitrogen, mixing bis-benzimidazole pyrene salt, potassium tert-butoxide and anhydrous tetrahydrofuran to prepare the free N-heterocyclic carbene compound; and (5) preparing an N-heterocyclic carbene zinc complex catalyst material: under the protection of nitrogen, mixing a free N-heterocyclic carbene compound, zinc halide and anhydrous tetrahydrofuran to prepare the N-heterocyclic carbene zinc complex catalyst material. Meanwhile, the invention further discloses applicatio
