Application

Diisobutylaluminum hydride solution (DIBAL-H) can be used as a reducing agent in the:
  • Hydrogenation of ester modified hydroxyl-terminated polybutadiene (HTPB) using cobalt catalyst.
  • Synthesis of primary 6-OH alcohols by regioselective ring opening of 4,6-benzylidene acetals of hexopyranosides using triphenylcarbenium tetrafluoroborate as a catalyst.
  • Conversion of an ester to alcohol.

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.
