Diisobutylaluminum hydride reducing agent is commonly used for the reduction of an ester to aldehyde.
Application
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.
Diisobutylaluminum hydride solution (25 wt. % in toluene) has been used for the reduction of imides:
