Significance

A simple one-pot synthesis of both potassium hydroxyaryl- and (hydroxyalkyl)aryltri­fluoroborates was developed. The respective hydroxyl groups are protected in situ via deproto­nation with t-BuLi. The hydroxylated trifluoroborates could be successfully subjected to Suzuki-Miyaura cross-coupling.
