Application

Diisobutylaluminum hydride solution (1M in toluene) has been used for the reduction of aziridine esters to the corresponding aldehydes. It has also been used in the synthesis of dialkylaluminum alkoxides from alcohols.
Used in Pd-catalyzed reductive debromination of secondary alkyl bromides. O-Debenzylation and ring opening of perbenzylated furanosides. Convenient in situ generation of HZrCp2Cl from ZrCp2Cl2 and DIBAL-H.
