ithium diisobutyL - Introduction
Lithium diisobutyl-tert-butoxyaluminum hydride is an organometallic compound with the chemical formula LiAlH(iBu)₂(O-t-Bu). It is a white solid that is soluble in non-oxidizing organic solvents such as n-hexane or ether. The following is a description of the properties, uses, preparation and safety information of the compound:
Nature:
- Lithium diisobutyl-tert-butoxyaluminum hydride is a strong reducing agent that reacts quickly with many organic compounds at room temperature.
-It is highly selective and has good reductive activity for ketones, aldehydes, acids, esters, amides and other functional groups.
- Lithium diisobutyl-tert-butoxyaluminum hydride for toluene and xylene and other non-reactive aromatic compounds of the reduction reaction is poor.
Use:
- Lithium diisobutyl-tert-butoxyaluminum hydride are widely used in reduction reactions in organic synthetic chemistry. It can reduce halogenated hydrocarbons, ketones, aldehydes and other compounds to the corresponding hydrocarbons or alcohols.
-It has important applications in drug synthesis, natural product synthesis and synthesis of heterocyclic compounds.
Preparation Method:
-The preparation of Lithium diisobutyl-tert-butoxyaluminum hydride is usually completed by adding diisobutyl aluminum chloride (iBu₂ AlCl) and tert-butyl sodium hydroxide (NaOt-Bu) to the ammonium hydrogen sulfate solution. The resulting white solid can be obtained by filtration and washing.
Safety Information:
- Lithium diisobutyl-tert-butoxyaluminum hydride is a strong reducing agent that reacts violently with substances such as water, acid and oxygen to produce flammable gases or violent explosions. Therefore, it is necessary to pay attention to safety measures during operation, such as low temperature and negative pressure.
-This compound has the characteristics of poor air and water stability. Avoid exposure to air and moisture during storage and operation. At the same time, care should be taken to avoid contact with flammable and oxidizing substances.
Finally, when using Lithium diisobutyl-tert-butoxyaluminum hydride, appropriate laboratory management and operating practices should be followed to ensure the safety of personnel and equipment.
