Lithium tetrahydrido(~2~H_4_)aluminate(1-)(CAS: 14128-54-2)

Lithium tetrahydrido(~2~H_4_)aluminate(1-) is a white or off-white solid with a high melting point. It has a molecular weight of approximately 56.9 g/mol. The compound is insoluble in water but demonstrates good solubility in organic solvents. It is highly reactive with acids and moisture, releasing hydrogen gas in the process.

Lithium tetrahydrido(~2~H_4_)aluminate(1-) is synthesized by the reaction of aluminum hydride (LHMDS) with lithium aluminum hydride (LAH) in a solvent like THF. The process requires careful control of reactant ratios and temperature to achieve high selectivity and yield.

Lithium tetrahydrido(~2~H_4_)aluminate(1-) is primarily used in the pharmaceutical industry for organometallic transformations and in the synthesis of complex organic compounds. It also finds applications in the polymer industry for catalysts and in the production of sensors and semiconductors.

When handling Lithium tetrahydrido(~2~H_4_)aluminate(1-), proper personal protective equipment (PPE) including gloves, goggles, and lab coat should be worn. This compound should be handled in a well-ventilated area or a fume hood to avoid inhalation of hydrogen gas. Spills should be managed carefully using appropriate absorbents, and the material safety data sheet (MSDS) should be consulted for detailed emergency procedures.
