bis-triphenylphosphine-palladium(II) chloride; In tetrahydrofuran; at 65℃; for 3.5h;Heating / reflux; | A 2-neck, 500 ML flask equipped with a reflux condenser and dropping funnel was charged with Pd(PPh3)2Cl2 (748.1 mg, 98%, 1.0 mmol) under a positive pressure of dry nitrogen.Dry THF (200 ML was added by cannula, followed by 1-iodo-2-(trimethylsilyl)acetylene (10.98 g, 48.99 mmol).The reaction was heated to reflux by a preheated oil bath and stannane 3 in 55 ML of dry THF was added dropwise over 2.5 h.The reaction was monitored by TLC, and was complete 1 h after the addition of stannane was complete.The reaction was cooled to room temperature, diluted with EtOAc (750 ML), stirred over 15% KF (aq) (750 ML) for 15 min and filtered through paper.The organic layer was isolated and the aqueous layer extracted with Et2O (3*300 ML).The combined organics were washed with water (500 ML) and brine (500 ML), dried (Na2SO4), filtered and reduced to a dark oil to give crude 4.The crude material was dissolved in IPrOH (75 ML) and 1 M NaOH (aq) (75 ML) and stirred at rt.The reaction was complete within 30 min.The reaction was poured into water (400 ML) and extracted with Et2O (3*400 ML).The combined organics were washed with water (400 ML) and brine (400 ML), Dried (Na2SO4), filtered and reduced to oil.The residue was purified by flash column chromatography (petroleum ether/Et2O 9:1 eluant) afforded 9.00 g of 5 (88%, two steps) as a colorless oil.Analytical TLC indicated a single compound (10% Et2O in petroleum ether eluant, Rf=0.48).

With copper(l) iodide; triethylamine;bis-triphenylphosphine-palladium(II) chloride; In acetonitrile; at 20℃; for 14h; | A solution of Example 1A (15 g, 0.02 mol) in acetonitrile (150 mL) and triethylamine (75 mL) at room temperature was treated with dichlorobis(triphenylphosphine)palladium(II) (0.994 g, 1.4 mmol), copper(I) iodide (0.115 g, 0.6 mmol), and 1-iodo-2-(trimethylsilyl)acetylene (5.9 mL, 0.0385 mol), stirred at room temperature for 14 hours, and concentrated. The concentrate was suspended in ether and filtered through diatomaceous earth (Celite). The filtrate was washed with water and brine, dried (Na2SO4), filtered, and concentrated. The concentrate was purified by flash column chromatography on silica gel with 85:15 hexanes/acetone to provide the desired product. |

75% | With n-butyllithium; In tetrahydrofuran; hexane; | EXAMPLE 3 [(dipentafluorophenylboryl)ethynyl]trimethylsilane 1.12 g (5 mmol) of (iodoethynyl)trimethylsilane are dissolved in 40 ml of tetrahydrofuran and cooled to -78 C. 3.2 ml of n-BuLi (5 mmol, 1.6M in hexane) are slowly added dropwise to this solution and the mixture is stirred for 2 hours. Subsequently, 1.90 g (5 mmol) of bis(pentafluorophenyl)boryl chloride are dissolved in 40 ml of tetrahydrofuran and likewise added dropwise to the above solution. The resulting suspension is slowly warmed to room temperature, forming a white precipitant. This is separated off by filtration. The solvent is removed from the filtrate obtained under reduced pressure. The remaining yellow oil is subsequently fractionally distilled. This gives 1.66 g (75% yield) of [(dipentafluorophenylboryl)ethynyl]trimethylsilane. |

83% | With bis-triphenylphosphine-palladium(II) chloride; copper(l) iodide; diisopropylamine; In tetrahydrofuran; at 20℃; for 4h;Inert atmosphere; | A solution of diisopropylamine (3.82 mL, 26.8 mmol), CuI (34.0 mg, 0.178 mmol), and Pd(PPh3)2Cl2 (46.8 mg, 0.178 mmol) in anhydrous THF (50 mL) was degassed with argon before 1-iodo-2-(trimethylsilyl)acetylene 9 (2.00 g, 8.92 mmol) and propargyl alcohol (0.619 mL, 10.7 mL) were added. The mixture was stirred at room temperature for 4 h. The brown reaction mixture was filtered through a plug of Celite, washing with EtOAc. The filtrate was concentrated in vacuo to give a brown residue. The crude material was purified by silica gel chromatography (gradient: 0-20% EtOAc in cyclohexane) to afford title compound 10 (1.36 g, 83% yield) as a brown oil. 1H NMR data obtained were consistent with those reported in literature.10 Rf=0.50 (20% EtOAc/cyclohexane); 1H NMR (400 MHz, CDCl3) delta=4.33 (d, J=6.0 Hz, 2H), 1.57 (t, J=6.4 Hz, 1H), 0.20 (s, 9H); IR numax(film) 3350, 2959, 2899, 2108, 1250, 1018, 843, 760 cm-1. |
