General description: Diisobutylaluminum hydride reducing agent is commonly used for the reduction of an ester to aldehyde.
Application: Diisobutylaluminum hydride solution (1.0 M in hexanes) can be used in the synthesis of potassium diisobutyl-t-butoxyaluminum hydride (PDBBA), a novel reducing agent for the chemoselective conversion of esters in the presence of nitriles. The DIBAL-triethylamine complex can reduce α-oxoketene dithioacetal to the saturated ketone.
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.
