Palladium-catalyzed cross-coupling reaction of alkenyl bromides with potassium alkyltrifluoroborates.


PMID 18196177

Abstract

The Suzuki-Miyaura-type cross-coupling reaction of potassium alkyltrifluoroborates with various alkenyl bromides in the presence of 10 mol % of PdCl(2)(dppf)·CH(2)Cl(2) and 3.0 equiv of Cs(2)CO(3) in aqueous toluene at 80 °C provided the desired compounds in 49-95% yields. A variety of functional groups in the potassium alkyltrifluoroborates were tolerated under the basic conditions.
