설명

애플리케이션

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.

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.
