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 ...
