Abstract: A novel general protocol for the preparation of functionalized (COOH, CHO, C(O)NHtBu, B(OH)2) tetraphenyl- and tetrakis(4'-biphenylyl)borates is reported. It involves four-fold halogen-lithium exchange in potassium tetrakis(iodophenyl)borates and tetrakis(4'-bromobiphenylyl)borate) using t-BuLi in THF at -78 °C… read more here.
