Application
Introduction of a (pinacolatoboryl)methyl group into aromatic rings
To a solution of bis(pinacolatoboryl)methane (B4103, 76 mg, 0.28 mmol, 2 eq.), 1-bromo-4-fluorobenzene (B0884, 25.0 mg, 0.142 mmol), and Pd[P(t-Bu)3]2 (B3161, 3.8 mg, 7.4 µmol, 5 mol%) in dioxane 1.5 mL is added 8 N KOH aq. (36 µL, 0.29 mmol, 2 eq.) at room temperature. The mixture is stirred at 25 °C for 2 h and filtered through a pad of silica gel with ether. Concentration gives the residue, and purification by silica gel column chromatography (hexane/EtOAc = 10/1) gives the product in 83% yield.
