Potassium organoselanyltrifluoroborates have been prepared from the corresponding dihalobenzene compounds in 56−92% yields through a facile one-pot, multicomponent reaction. The microwave-promoted Suzuki−Miyaura cross-coupling reaction of these substrates with various aryl and alkenyl bromides in the presence of 3.0 mol % of Pd(PPh3)4 and 3.0 equiv of K2CO3 in aqueous 1,4-dioxane at 130 °C provided the desired compounds in 54−91% yields.
