General procedure: To a round-bottom flask was charged with the correspondingaromatic halogen (1.0 equiv), the corresponding boronic acid(1.05-1.25 equiv), Pd(dppf)Cl2 (0.05 equiv) and base Na2CO3 (2.0equiv) under nitrogen atmosphere, then 1,4-dioxane (14 mL) andwater (2 mL) were added and the vessel was immediately sealed tightly. The resulting mixture was heated at 95 C for a period time (usually 2-6 h) until the completion of the reaction as monitoredby TLC. The cooled mixture was diluted with water and exhaustively extracted with ethyl acetate (30 mL 3). The organic phase was washed by brine, dried over anhydrous Na2SO4, and evaporated under reduced pressure. The residue was purified by chromatography on silica gel using ethyl acetate/petroleum ether as the eluent to afford the products.
