Ruspic, Christian Nembenna, Sharanappa Hofmeister, Anja Magull, Jörg Harder, Sjoerd Roesky, Herbert W. A Well-Defined Hydrocarbon-Soluble Calcium Hydroxide:  Synthesis, Structure, and Reactivity Controlled hydrolysis of a (β-diketiminate)calcium-amide gave a heteroleptic (β-diketiminate)calcium-hydroxide complex that is remarkably stable against ligand exchange and formation of Ca(OH)<sub>2</sub>. The structure of this dimeric complex shows OH<sup>-</sup> units that symmetrically bridge the Ca<sup>2+</sup> ions. This hydrocarbon-soluble calcium hydroxide reacted rapidly with CO<sub>2</sub> to produce a gel from which amorphous CaCO<sub>3</sub> slowly separated. This reaction behavior allows for sol−gel coating with CaCO<sub>3</sub> from an organic solvent. Reaction with benzophenone did not lead to nucleophilic attack of OH<sup>-</sup> to the carbonyl but gave a red benzophenone adduct instead.
