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
Fine tuning via salt formation: The present work summarizes the synthesis and characterization of thymol-metal/ammonium salts as representative phenol-containing bioactive molecules. The solubility, thermal properties, and evaporation rate of thymol salts were studied relative to native thymol. The in vitro release of copper from Cu-thymol in water and in solution of various pH values was thoroughly
