One-pot construction of novel structures from readily available starting materials
RIKEN CSRS and Organometallic Chemistry Laboratory researchers have developed a simple method for the synthesis of a family of lithium boracarbonate compounds which are potential battery electrolytes using carbon dioxide as a key chemical component. The reaction was achieved in the presence of a copper catalyst via selective coupling of carbon dioxide, a boron compound, aldehydes and a lithium alkoxide in a one-pot process. The resulting products are composed of a lithium borate unit and a cyclic carbonate unit in one molecule, which resembles a combination of lithium borate electrolytes and carbonate solvents commonly used in lithium-ion batteries.
These findings may lead to the development of new solvent-free electrolytes for lithium-ion batteries, and could also contribute to the development of new chemical processes for efficient utilization of carbon dioxide.
