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). It can be used for various homogeneous reductions such as alkynes to alkenes, esters or nitriles to aldehydes. It is available commercially as the neat reagent and as a solution in several different solvents (hexane, dichloromethane, tetrahydrofuran, etc.). The neat reagent is a liquid and is supplied in metal cylinders. It is pyrophoric and highly reactive and therefore must be handled with great care. The molar solutions in organic solvents are more stable and easier to handle provided that the normal precautions are taken for working with air-sensitive compounds. They must all be handled in an atmosphere free from oxygen and water. Commonly used solvents for diisobutylaluminium hydride are dichloromethane, diglyme, dioxane and tetrahydrofuran. Even when the substrate is not completely soluble in these solvents successful reductions can be accomplished.화학적 성질
Diisobutylaluminium hydride, also known as Dibal. colorless liquid. Viscosity 18.0mPa-s(25℃). Reacts violently with water to form hydrogen and isobutane. Tetrahydrofuran is not suitable as Dibal solvent, because the two react to produce coordination compounds. Diisobutylaluminium hydride is a useful reducing agent in organic synthesis. It can reduce ketones, carboxylic acids and esters to the corresponding alcohols. Dibal can also reduce lactones to o-hydroxy lactones.용도
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.
Safety Profile
Mddly toxic by inhalation. Dangerous fire hazard; iptes spontaneously in air. To fight fire, do not use water, foam, or halogenated extinguisking agents. See also HYDRIDES and ALUMINUM COMPOUNDS.디이소부틸알루미늄하이드라이드 준비 용품 및 원자재
