EXAMPLE FIFTY-FOUR: General Procdure for Pd-Catalyzed Nitrations of Aryl Chlorides and Aryl Sulfonates (Figures 20 and 21); An oven-dried schlenk tube, which was equipped with a magnetic stir bar and fitted with a rubber septum, was charged with the Pd₂(dba)₃ (0.5 mol %), ligand (6, 25, 26, or 27) (1.2 mol %), and NaNO₂ (138 mg, 2.0 mmol) (aryl halides* that were solids at room temperature were added with the catalyst). The vessel was evacuated and backfilled with argon (this process was repeated a total of 3 times) and then the aryl halide* (1.0 mmol), tris(3,6-dioxaheptyl)amine (5 mol %), and te/t-butanol (2 mL) were added via syringe. The reaction vessel was sealed with a Teflon screw cap and heated to 110 ⁰C for 24 h. The solution was cooled to room temperature, diluted with Ethyl acetate, washed with water, and purified via flash chromatography.* Includes aryltriflates and arylnonaflates.
