90% | Stage #1: With iodine; magnesium In tetrahydrofuran at -50℃; Reflux Stage #2: Heating |
The reaction flask was charged with 0.10 mol (0.1 eq) m-bromotoluene, 1.1 mol (1.1 eq) magnesium turnings, a few grains of simple iodine, 800 ml THF, stirred, and warmed to reflux. When Grignard initiated, 0.90 mol (0.9 eq) of m-bromotoluene was continuously added dropwise under the reflux condition, and the reaction of refluxing and keeping warm was completed. The reaction time is reached and the temperature is reduced to -50.0°C. 2.2 mol (2.2 eq) of trimethyl borate was added dropwise, and the reaction was incubated until the reaction of the raw materials was complete, and the temperature was raised and water was added. Hydrochloric acid was added dropwise, the pH was adjusted to 1-2, the reaction was incubated, the reaction time was reached, rotary evaporation, suction drying, and beating and purification were performed to obtain 0.90 mol of 3-methylphenylboronic acid as a white solid, 0.03percent of water, and a purity of 98.86percent. The yield was 90.0percent. |

General procedure: To a solution in THF (4 mL) of DIPAB (863 mg, 7.5 mmol) and Mg (182 mg, 7.5 mmol) were added a PhMgBr 1M THF solution (375 μL, 375μmol) at room temperature. After 10 min, 30 mL of anhydrous THF were added followed by the arylbromide (5 mmol). The reaction mixture was cooled down to 0 °C and quenched slowly with 7 mL of MeOH. After 1h, volatile were removed under reduced pressure and the resulting solid was dissolved in 1N HCl/MeOH (7/3). After 1h at room temperature, 100 mL of AcOEt were added, the organic phase was washed with 1N HCl (30 mL) and brine (3×30 mL). Organic phases were concentrated under reduced pressure yielding a solid which was recrystallized from H2O. |

General procedure: Arylboronic acid 1 (0.5 mmol) and K2CO3 (1 mmol, 138.0mg) were added to a 20 mL Schlenk-tube equipped with amagnetic stir bar. The tube was evacuated twice and backfilledwith N2. MeCN (2 mL) and I2 (0.75 mmol, 191 mg)were added to the tube at r.t. under a stream of N2, and thetube was sealed and placed into a pre-heated oil bath at 80 °Cfor 8–12 h. The resulting solution was cooled to r.t., and thenarylboronic acid 1′ (0.75 mmol) and Pd(OAc)2 (0.025 mmol, 5.6 mg) were added, and the mixture stirred at 80 °C for 12–16 h. The resulting solution was cooled to r.t. and H2O (10mL) was added. The aq layer was extracted with EtOAc(3 × 5 mL). The combined organic phase was dried overanhydrous Na2SO4, filtered and concentrated by rotaryevaporation, and the residue was purified by columnchromatography on silica gel to provide the desired product3a–v.
