Application: Diisobutylaluminum hydride solution (1M in THF) is a powerful reducing agent. It can be used in the following reactions:• Synthesis of trans-alkene isosteres of protected dipeptides.• To generate bis(1,5-cyclooctadiene)nickel(0) (Ni(cod)2) in situ, which can catalyze the conjugate addition of ethenyltributyltin to 2-propenal to form tert-butyldimethyl[((E)-1,4pentadienyl)oxy]silane.• Reduction of the arylpropiolate esters to give the corresponding propargyl 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.
