---|---|---|
99% | With potassium carbonate; In water; at 75℃; for 5h; | General procedure: In air, aryl halide (0.2 mmol), arylboronic acid (0.22 mmol),K2CO3 (0.3 mmol), 5 ml of distilled water, and 2 mg of catalystwere combined in a 10 ml round bottom flask. The reactionmixture was magnetically stirred and the temperature wasmaintained at 75 C in an oil bath. Reaction progress was monitoredby TLC. After reaction was completed, the reaction mixturewas cooled to room temperature and filtrated. The filtratedsolid was washed with water (35 ml) and dissolved withethyl acetate. The catalyst was separated by filtration, washedwith water, and dried in vacuum. The combined organic phasewas dried with anhydrous MgSO4, and the solvent was removedunder reduced pressure to give the product. |
95% | With 1-phenylethanone-O-(4-chloro-phenyl)oxime; tetrabutylammomium bromide; potassium carbonate; palladium dichloride; In water; at 27℃; for 6h;Green chemistry; | General procedure: All the reactions were carried out in open atmosphere. A mixture of arylbromide (0.5 mmol), aryl boronic acid (0.55 mmol), K2CO3 (1 mmol), PdCl2(1 mol %), ligand (2 mol %), TBAB (0.5 mmol), and water (4 mL) was stirred atroom temperature for the indicated time in a 25 mL round bottom flask. Theprogress of the reaction was monitored using TLC (Merck silica gel 60F254plates) under UV light. After completion, the reaction mixture was diluted withbrine (10 mL) and extracted with ether (3 10 mL). The combined extract wasdried over anhydrous Na2SO4. After evaporation of ether under vacuum, theproduct was isolated by short-chromatography {silica gel (60-120 mesh), ethylacetate-hexane; 0.5:9.5}. The isolated products were confirmed by comparingtheir 1H and 13C NMR and mass spectral data with reported samples |
94% | With palladium diacetate; sodium carbonate; In 1,2-dimethoxyethane; for 2.5h;Inert atmosphere; Reflux; | (b) A mixture of 4-chlorobenzeneboronic acid (19.4 g, 1 equiv), 4-bromobenzaldehyde (22.9 g, 1 equiv), palladium(II) acetate (1.4 g, 0.05 equiv) aqueous sodium carbonate (30.3 g in 144 ml solution, 2 equiv) and dimethoxyethane (500 ml) was stirred at reflux under argon for 2.5 h, then evaporated to low volume and diluted with dichloromethane. Workup continued as in (a) above to give identical material (25.2 g, 94%). 1H-NMR (CDCl3) delta 10.05 (1H, s), 7.96 (2H, d), 7.73 (2H,d), 7.57 (2H, d), 7.46 (2H, d); MS (AP+) found (M+1)=217, C13H935ClO requires 216. |
90% | With [2,6-(iPr)2C6H3-N=C(Ph)-C(Ph)(Me)-OH]PdCl2; sodium carbonate; In ethanol; water; at 60℃; for 2h; | General procedure: In a round bottle, palladium complexes (0.01 mol% mmol), aryl halides (1.0 mmol), arylboronic acid (1.2 mmol), base (2.0 mmol) and 4 ml of solvent were added with a magnetic stir bar. The reaction mixture was carried out at the described temperature for the required time, and then the solvent was removed under reduced pressure. The residual was diluted with Et2O (5 ml), followed by extraction twice (2 × 5 ml) with Et2O. The organic layer was dried with anhydrous MgSO4, filtered and evaporated under vacuum. The crude products were purified by silica-gel column chromatography using petroleum ether-ethyl acetate (20/1) as an eluent, and the isolated yield was then calculated based on the feeding of the aryl halide. The isolated corresponding products were characterized by 1H NMR and 13C NMR. |
90% | With sodium hydroxide; In water; at 80℃; for 0.5h;Inert atmosphere; Green chemistry; | General procedure: 5 mL distilled water was taken in a 25 mL round bottom flask, equipped with a magnetic bar and a water condenser, and deoxygenated with nitrogen gas for 5 min. Aryl halide (1 mmol), arylboronic acid (1.2 mmol), NaOH (1.2 mmol) and Pd-gamma-Fe2O3 (20 mg) were added to it and allowed to stir at 80 C under nitrogen atmosphere. The progress of the reaction was monitored by TLC. After completion of the reaction, the catalyst was recovered using an external magnet. The reaction mixture was extracted with EtOAc (3 x 10 mL) and the combined organic layer was washed with water, brine solution and dried over anhydrous Na2SO4. The crude product was concentrated in a rotary evaporator and purified by column chromatography. The purified compounds were characterized by 1H and 13C NMR. |
84% | With C26H18Cl2N6NiO2; potassium carbonate; In toluene; for 8h;Reflux; | General procedure: (1.0 mmol) and K2CO3 (2.0 mmol) in toluene (10 mL),1(0.5 mol%) were added. The resultant mixture was refluxed for 8 h, there action mixture was then cooled to room temperature, H2O(10 mL) added and the organic layer was extracted with EtOAc(3x20 mL). The solvent was stripped off and the remaining residue was purified by column chromatography (n-hexane-EtOAc) to yield the pure product. The products were confirmed by 1H NMR. For the double cross-coupling reaction the procedure was similar to that mentioned above where dibromide (1.0 mmol),arylboronic acid (2.0 mmol), 1 (1.0 mol%) and K2CO3 (4.0 mmol) in toluene (10 mL) were used. |
80% | With 3,5-di-tert-butyl-2-hydroxybenzaldehyde; potassium carbonate; palladium dichloride; In ethanol; water; at 20℃; for 2h; | General procedure: To a round bottle with a magnetic stir bar, ligand (0.01% mmol), PdCl2 (0.01% mmol), aryl halides (1.0 mmol), phenylboronic acid (1.2 mmol), K2CO3 (2.0 mmol) and 6 ml of solvent were added. The reaction mixture was conducted at room temperature for the required time, and then the solvent was removed under reduced pressure. The residual was diluted with Et2O (5 mL), followed by extraction twice (2×5 mL) with Et2O. The organic layer was dried with anhydrous MgSO4, filtered and evaporated under vacuum. The conversions rates were analyzed by gas chromatography, based on the peak area normalization method. The corrected factor was determined by samples against a standard of n-heptane. The crude products were purified by silica-gel column chromatography using petroleum ether-ethyl acetate (20:1) as an eluent, and the isolated yield was then calculated based on the feeding of the aryl halide. The isolated corresponding products were characterized by 1H NMR and 13C NMR. |
