cis-Dihydroxylation of Unsaturated Potassium Alkyl- and Aryltrifluoroborates
摘要:
The cis-dihydroxylation of olefin-containing potassium alkyl- and aryltrifluoroborates proceeds readily in moderate to excellent yields. The resulting diols are efficient coupling partners in Suzuki-Miyaura-type reactions with both alkenyl and aryl bromides.

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 degrees C provided the desired compounds in 49-95% yields. A variety of functional groups in the potassium alkyltrifluoroborates were tolerated under the basic conditions.
