A facile one-pot preparation of organoselanyltrifluoroborates from dihalobenzenes and their cross-coupling reaction.
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(PPh(3))(4) and 3.0 equiv of K(2)CO(3) in aqueous 1,4-dioxane at 130 degrees C provided the desired compounds in 54-91% yields.
