The Suzuki-Miyaura coupling of potassium aryltrifluoroborates with aryl bromides in water is promoted by [bmim]PF6 using Pd(OAc)2 as a catalyst and Na2CO3 as a base under air. The efficiency of the catalytic system depends on the quantity of [bmim]PF6. A wide range of biaryls and polyaryls can be easily prepared in very good yields.
