Tetraphenoxyborates are reliably prepared in a two‐step sequence, exploiting less corrosive reagents like boric acid and the corresponding phenols. The broad scope of this transformation is demonstrated in 22 examples. Several solid‐state structures reveal the preferential conformation of the phenoxy moieties allowing cation interaction. Furthermore, a novel architecture of a phenoxy‐substituted tetraborate was found. Surprisingly, the tetraphenoxyborates exhibit a good stability in neutral and basic media.
