Question

what is the speciality of DIBAL - H reagent?...........hey guys.....don't copy on google..​

Answer 1

Answer:

At ordinary temperatures, DIBAL-H reduces variety of carbonyl compounds, like aldehydes, ketones, carboxylic acids and esters, to corresponding alcohols.  These reductions are chemoselective as well as stereospecific.

One or less than one equivalent of DIBAL-H is required for the reductions of aldehydes or ketones.

CAS Number: 1191-15-7

Molecular Weight: 142.22 g/mol

Appearance: Colorless liquid

 Diisobutylaluminum hydride (DIBAL-H) is an organoaluminum reagent typically used for the reduction esters or nitriles to aldehydes. DIBAL-H is usually obtained and used as a 1.0 M solution in a wide variety of solvents (ex. DCM, THF, hexanes, heptane, toluene, and cyclohexane). Some of the advantages of using DIBAL-H over other organoaluminum reagents include its greater selectivity, its ease of handing as a liquid, and its miscibility with a wide range of solvents (including hydrocarbons and aromatic solvents).
