<i>cis</i>-Dihydroxylation of Unsaturated Potassium Alkyl- and Aryltrifluoroborates

Abstract

[reaction: see text] 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.
