YieldReaction ConditionsOperation in experiment
39% With 2.9-dimethyl-1,10-phenanthroline; oxygen; copper diacetate; silver sulfate; In dimethyl sulfoxide; at 140℃; under 760.051 Torr; for 20h;Schlenk technique; Green chemistry; General procedure: An oven-dried Schlenk tube equipped with a stir bar was charged with aryl carboxylic acid (0.2 mmol), Ag2SO4 (6.2 mg, 0.02 mmol, 0.1 equiv.), Cu(OAc)2 (36.3 mg, 0.2 mmol, 1 equiv.), K4Fe(CN)6 (13.2 mg, 0.036 mmol, 0.18 equiv.) and 2,9-dimethyl-1,10-phenanthrolinium (12.5 mg, 0.06 mmol, 0.3 equiv.). The tube was fitted with a rubber septum, and then it was evacuated and refilled with dioxygen three times. Under dioxygen, DMSO (4 mL) was added via syringe. The rubber septum was replaced with a Teflon screwcap under dioxygen flow, and the Schlenk tube was pressurized to 1 atm. With stirring, the reaction mixtures were heated at 140 C for the indicated amount of time (unless otherwise specified). After cooling to room temperature, the reaction mixtures were diluted with ether (10 mL) and filtered through a pad of silica gel that was then washed with ether (10 mL *3). The combined organic phase was washed with brine (20 mL *2), dried over Na2SO4, filtered and concentrated in vacuo. The resulting residue was purified using flash column chromatography over silica gel to provide the corresponding product with ethyl acetate/hexane as eluent.
