In a three-neck flask, the catalyst ligand 1-(2-carboxyethyl)-3-formyltriacyl-1H-imidazol-3-ammonium chloride (1.03 mmol), nickel acetylacetonate (1.01 mmol), and lithium tert-butoxide (31.2 mmol) were added to tetrahydrofuran (100 mL). Isopropyl magnesium chloride (14.6 mL, 1.7 M ether solution, 24.8 mmol) was subsequently added under nitrogen protection and agitation. Add 1-bromo-3-chloronaphthalene after 0.5 h and stir at 0 °C for 2 h. Finally, 3-chloro-1-(1,1-dimethylethyl)Naphthalene was obtained after purification.
