Alkoxyalkyl‐Substituted β‐Diketonate Complexes of Barium and Copper: Evidence for Inter‐ and Intramolecular Stabilization

Useful in the synthesis of low-valent barium compounds, the ligand HL is prepared by the Claisen condensation of MeO2C(CH2)OMe with pinacolone. [BaL2], a base-free barium(II) complex, is formed in the reaction of HL with barium metal. This compound is monomeric in solution and a liquid at room temperature. Such compounds are potential sources of barium for the vapor deposition of thin films for electronic materials.
