| 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. |
| 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. |
