Descripción

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.

Utilizada en la desbromación reductiva catalizada por Pd de los alquil bromuros secundarios. O-desbencilación y apertura del anillo de los furanósidos perbencilados. Cómoda generación in situ de HZrCp₂Cl a partir de ZrCp₂Cl₂ y DIBAL-H.
