Reaction Conditions:

with bis{1,1’-diphenyl-3,3’-methylenediimidazoline-2,2’-diylidene}nickel(II) dibromide;potassium tert-butylate in 1,4-dioxane at 90; for 4 h;Catalytic behavior;Inert atmosphere;Schlenk technique;Buchwald-Hartwig Coupling;Reagent/catalyst;

Steps:

5.4.1. General procedure for the Buchwald-Hartwig reaction
General procedure: Under an N₂ atmosphere, KO^tBu (1.3 mmol), complex 1 (1 mol %), dioxane (2 ml), amines (1.3 mmol) and aryl chlorides (1.0 mmol) were successively added into a Schlenk tube. The mixture was stirred vigorously at 90 °C for 4 h. Then the solvent was removed under reduced pressure and the residue was purified by column chromatography on silica gel (eluent: PE/EA = 15:1) to give the pure products. The reported yields are the average of two runs.
