YieldReaction ConditionsOperation in experiment
With potassium acetate;dichloro(1,1'-bis(diphenylphosphanyl)ferrocene)palladium(II)*CH2Cl2; In 1,4-dioxane; at 85℃; for 4.0h; A suspension of 1 -bromo-4-(methylsulfinyl)benzene (5.48 g, 25 mmol), bis(pinacolato)diboron (6.98 g, 27.5 mmol), dioxane (100 mL), potassium acetate (7.36 g, 75 mmol) was degassed and PdCl2(dppf)-CH2Cl2 adduct (0.204 g, 0.250 mmol) was added. The mixture was heated at 85 C for 4 h. It was cooled and most of the solvent was removed by evaporation under diminished pressure. The residue was passed through a short pad of SiO2 eluting with 2:1 EA:H to give 2-(4-bromophenyl)-4,4,5,5-tetramethyl-l,3,2-dioxaborolane. lH NMR (500 MHz, acetone-d6): δ 7.9 (2H, d), 7.7 (2H, d), 2.75 (3H, s), 1.4 (12H, s) ppm.
