YieldReaction ConditionsOperation in experiment
68% With copper(l) iodide; lithium methanolate; bis[2-(diphenylphosphino)phenyl] ether In dimethyl sulfoxide at 50℃; for 16 h; General procedure: Phenylpropiolic acid (439 mg, 3.0 mmol), B2pin2 (763 mg, 3.0 mmol), lithium methoxide (23 mg, 0.6 mmol), copper iodide (57 mg, 0.3 mmol), and Dpe-Phos (324 mg, 0.6 mmol) were added to a vial containing DMSO (5 mL). The suspension was stirred for 16 h at 50 °C. The reaction was monitored by TLC, and after the completion of the reaction, the reaction mass was cooled to 25–28 °C and quenched into a mixture of 50 mL of water and 50 mL of ethyl acetate. The ethyl acetate layer was washed with water (2 × 25 mL), brine (2 × 25 mL), and then dried over Na2SO4. Evaporation of the solvent under reduced pressure provided the crude product, which was purified by column chromatography (hexane:EtOAc = 9.5:0.5).
57% With copper(II) trifluoroacetate; sodium carbonate In 1,4-dioxane at 80℃; for 18 h; Inert atmosphere General procedure: A Schlenk tube with a magnetic stirring bar was charged with 3-phenylpropiolic acid (1a, 68 mg, 0.5 mmol), bis(pinacolato)diboron (2a, 152 mg, 0.6 mmol), Cu(TFA)2 (29 mg, 10 molpercent), Na2CO3 (127 mg, 1.2 mmol), and 1,4-dioxane (2 mL) under N2. The reaction mixture was stirred at 80 °C for 18 h (monitored by TLC and GC). Upon completion of the reaction, the reaction mixture was then cooled to ambient temperature, diluted with ethyl acetate (20 mL), filtered through a plug of silica gel, and washed with ethyl acetate (20 mL). The organic layer was washed with saturated brine (20 mL×2) and dried over anhydrous Na2SO4. The solvents were removed via rotary evaporator and the residue was purified by flash chromatography (silica gel, ethyl acetate: petroleum ether=1:30) to give 89.7 mg of desired product 3a in 78 percent yield as a colorless oil. 1H NMR (400 MHz, CDCl3): δ 7.48–7.50 (m, 2H), 7.41 (d, 1H, J=18.5Hz), 7.29–7.32 (m, 3H), 6.18 (d, 1H, J=18.4Hz), 1.32 (s, 12H). 13C NMR (100 MHz, CDCl3): δ 148.5, 136.4, 127.9, 127.5, 126.0, 82.3, 23.8
