YieldReaction ConditionsOperation in experiment
91% With bis-triphenylphosphine-palladium(II) chloride; potassium phosphate In 1,4-dioxane; water at 95℃; Inert atmosphere General procedure: The halo aryl (1.0 equiv) was dissolved in a mixture of water:dioxane (1:1). The boronic acid or ester(1.5 equiv) and potassium phosphate (5.0 equiv) were added. The solution was degassed byvacuum/argon cycles (10 times) before addition of PdCl2(PPh3)2 (10 molpercent) and further degassed (5times). The resulting mixture was stirred at 95 °C under argon atmosphere for 16-20 hours. Thereaction mixture was filtered through Celite and diluted with water (approx. 30 mL) before washingwith chloroform (3 x 30 mL). If not stated otherwise, the aqueous phase was concentrated underreduced pressure and applied to a C18 precolumn before purification on a 10g or 60 g C18 column witha gradient of acetonitrile in water (10-100percent) to yield the desired product.

The Schlenk tube was sealed with a Teflon valve and the reaction mixture was stirred at [110 °C] for 23 h. The resulting suspension was allowed to reach room temperature, poured into 10percent aq HCl (20 mL), and extracted with dichloromethane [(3X 15] mL). The combined organic phases were dried [(NA2SO4)] and concentrated. The residue was dissolved in dichloromethane (50 mL) and washed with an aqueous solution of 1percent HCl and 1percent [NA2SO3.] The aqueous phase was extracted with with dichloromethane [(2X20] mL). The organic phases were combined, dried (Na2SO4) and concentrated. The solid residue was washed with hexane [(3X15 ML)] and dried to provide 3-iodobenzoic acid (222 mg, 90percent yield) as white, fine needles.

80% With N-iodo-succinimide; [4,4’-bis(tert-butyl)-2,2’-bipyridine]bis[3,5-difluoro-2-[5-(trifluoromethyl)-2-pyridinyl]phenyl]iridium(III) hexafluorophosphate; iodine; caesium carbonate In 1,2-dichloro-ethane at 50℃; for 24 h; Inert atmosphere; Irradiation; Sealed tube General procedure: To a 15 mL test tube with septum Cs2CO3 (0.6 mmol, 195 mg), aromaticcarboxylic acid (1) (0.3 mmol), [Ir(dF(CF3)ppy)2dtbbpy]PF6 (D) (6 μmmol, 6.7 mg), NIS (1.5mmol, 337.5 mg) and I2 (60 μmol, 20 molpercent) were added. The tube was evacuated and backfilledwith argon for three times, and then 3 mL of dry DCE was added through a syringer under argon.The tube was sealed with Parafilm Mr® and placed in an oil bath with a contact thermometer, andthe reaction was carried out at 50 °C under irradiation with 6 × 5 W blue LEDs (λmax = 455 nm).After 24 h or 36 h, the resulting mixture was filtered through a 2 cm thick pad of silica, and thesilica was washed with DCM) (50 mL). The filtrate was collected and the solvent was removed invacuo. The crude residue was purified by silica gel flash column chromatography to provide thetarget product (2). (Note: The reaction was very sensitive to moisture, and the yields sharplydecreased to less than 5percent when 0.01 equivalent of H2O was added to the reaction system).

The cold reaction mixture was washed with 1 M aq Na2S03 (2 x 5 mL), dried over Na2S04, filtered through short neutral alumina pad and concentrated in vacuo to give 0.35 g (61percent) of 3- bromoiodobenzene. The combine aq sodium sulfite washings were extracted with DCM (3 x 10 mL), carefully acidified with cone, hydrochloric acid to pH 2 and stirred at 0-5 °C for 2 h. The precipitated solid was filtered off, washed on the filter with cold water and dried in vacuo to recover 0.12 g (30percent) of 3- bromobenzoic acid.

The reaction mixture was diluted with ethyl acetate (30 mL), then washed with water (20 mL), followed by brine (20 mL). The organic layer was dried over anhydrous sodium sulfate and carefully concentrated under reduced pressure. The resulting residue was then purified by flash column chromatography on silica gel with 0:4 to 1:4 dichloromethane/hexane as eluent to yield the desired product 5a as a colorless oil.

89% With (1,1'-bis(diphenylphosphino)ferrocene)palladium(II) dichloride; potassium acetate In 1,4-dioxane at 110℃; Inert atmosphere To a degassed souDon of 1,4-doxane (0.1 M), under an atmosphere of ntrogen,was addedthe benzoc acid (1 eq.), bs(pnacoato)dthoron (1 .5 eq.), and KOAc (4.4 eq.) sequenUafly.The mixture was degassed once again and then PdC2(dppf) (5 mopercent) was added. Theresutng souUon was heated to 110°C overnight. The sovent was removed in vacuo to givea dark gummy residue, which was taken up nto EtOAc and H20. The organic ayer was separated and the aqueous was further extracted with EtOAc (2x). The combined organic ayers were washed with 2 M HC, dried over MgSO4 and concentrated in vacuo to give a dark brown sohd. The resutng sohd was trtu rated wth petroeum benzne to afford the Uflecompound.

YieldReaction ConditionsOperation in experiment
90% With palladium 10% on activated carbon; sodium carbonate In water; isopropyl alcohol at 20 - 70℃; for 4.5 h; The Suzuki coupling was carried out according to the method of Dyer et al. (Tetrahedron Letters, 2001, 42, 1765-1767). Commercially available 4-(Trifluoromethyl)phenylboronic acid (95.9g, 505 mmol) and 3-bromobenzoic acid (100.5g, 500 mmol) were suspended in 2-propanol:water (1:4, 500 mL). 10percent Pd/C (4.8g) was added. Aqueous Na2CO3 (250 mL, 20percent by wt.) was then added slowly (to control CO2 evolution) to the above mixture while vigorously stirring. The resulting mixture was stirred at room temperature for 30 min and then heated at 70C for 4 hours. The Pd/C was filtered and rinsed with 20percent aqueous Na2CO3 solution (20mL). The filtrate was acidified to pH~4 with 6N HCl, and the resulting white solid was collected by filtration and dried in vacuo. The crude product was dissolved in acetone (1.4L) then an equal volume of distilled water was added. The resulting white precipitate was collected by filtration and dried in vacuo. 120.2 g of coupled product 8.1 was acquired (yield: 90percent). MS ESI m/e: 267 (M-H). 1H NMR (500MHz) (DMSO) 13.17 (1H, s); 8.25 (1H, s); 8.03-7.99 (2H, m); 7.95 (2H, d); 7.85 (2H, d); 7.66 (1H, t). mp: 197 °C - 200 °C.

YieldReaction ConditionsOperation in experiment
98% With bis-triphenylphosphine-palladium(II) chloride; potassium phosphate In 1,4-dioxane; water at 95℃; Inert atmosphere General procedure: The halo aryl (1.0 equiv) was dissolved in a mixture of water:dioxane (1:1). The boronic acid or ester(1.5 equiv) and potassium phosphate (5.0 equiv) were added. The solution was degassed byvacuum/argon cycles (10 times) before addition of PdCl2(PPh3)2 (10 molpercent) and further degassed (5times). The resulting mixture was stirred at 95 °C under argon atmosphere for 16-20 hours. Thereaction mixture was filtered through Celite and diluted with water (approx. 30 mL) before washingwith chloroform (3 x 30 mL). If not stated otherwise, the aqueous phase was concentrated underreduced pressure and applied to a C18 precolumn before purification on a 10g or 60 g C18 column witha gradient of acetonitrile in water (10-100percent) to yield the desired product.
