Applicazioni

Diisobutylaluminum hydride reduces chiral ?-silyloxy esters to the corresponding enantiomerically-pure hydroxy aldehydes. I t is used in Pd-catalyzed reductive debromination of secondary alkyl bromides, O-Debenzylation and ring opening of perbenzylated furanosides and convenient in situ generation of HZrCp2Cl from ZrCp2Cl2 and DIBAL-H.

Note

Store in cool place. Keep container tightly closed in a dry and well-ventilated place. It is sensitive to moisture and air. Store under dry inert gas.
