Question 1

What is the Diisobutylaluminium hydride?

Accepted Answer

Diisobutylaluminium hydride is Clear solution, while it's Molecular Formula is C8H19Al. Clear solution Diisobutylaluminum hydride (DIBAL-H) is a common reducing agent to reduce aldehydes, ketones, esters, acids and acid chlorides to the corresponding alcohols. Some of the applications are:Synthesis of a-acetoxy ethers by reduction and subsequent acetylation of esters.Synthesis of coniferyl, sinapyl, and p-coumaryl alcohol by selective reduction of corresponding cinnamate esters.Reduction of secondary phosphine oxides (SPOs) to the corresponding phosphines.DIBAL-H can also be used in the hydroalumination of alkene and alkynes.

Question 2

What is the CAS number for Diisobutylaluminium hydride?

Accepted Answer

The CAS number of Diisobutylaluminium hydride is 1191-15-7.

Question 3

What is Diisobutylaluminium hydride (1191-15-7) used for?

Accepted Answer

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.InChI:InChI=1/2C4H9.Al.H/c2*1-4(2)3;;/h2*4H,1H2,2-3H3;;/q;;+1;-1/rC8H18Al.H/c1-7(2)5-9-6-8(3)4;/h7-8H,5-6H2,1-4H3;/q+1;-1
