Abstract
3,5-Dimethylphenylmagnesium bromide reacts with triisopropyl borate to give 3,5-dimethylphenylboronic acid and bis(3,5-dimethylphenyl)borinic acid. Conditions were found which allowed the clean preparation of bis(3,5-dimethylphenyl)borinic acid, which was coupled with a vinyl triflate using Suzuki cross-coupling conditions. Both aryl groups were efficiently transferred from boron in the Suzuki step.
