| Hazard Information | Back Directory | [Description]
Diisobutylaluminium hydride (DIBALH, DIBAL, DIBAL-H or DIBAH) is a reducing agent with the formula (i-Bu2AlH)2, where i-Bu represents isobutyl (-CH2CH(CH3)2). This organoaluminium compound was investigated originally as a co-catalyst for the polymerization of alkenes. | [Chemical Properties]
Clear solution | [Uses]
Diisobutylaluminum hydride is commonly used as a reducing agent in organic synthesis.
Diisobutylaluminum hydride can be used in the following protocols:
As a promotor of Tishchenko reaction of aldehydes.
Conversion of benzylidene acetals of 1,2-and 1,3-glycols to the corresponding monobenzyl ethers of the glycols.
To generate a novel chiral reducing agent based on (S)-proline for the asymmetric reduction of prochiral ketones. | [Flammability and Explosibility]
