| Application: | Diisobutylaluminum hydride (DIBAL-H) is a common reducing agent to reduce aldehydes, ketones, esters, acids and acid chlorides to the corresponding alcohols. Some of the applications are: • Synthesis of α-acetoxy ethers by reduction and subsequent acetylation of esters. • Synthesis of coniferyl, sinapyl, and p-coumaryl alcohol by selective reduction of corresponding cinnamate esters. • Reduction of secondary phosphine oxides (SPOs) to the corresponding phosphines. • DIBAL-H can also be used in the hydroalumination of alkene and alkynes. |
| 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. |
