应用
二异丁基氢化铝溶液（DIBAL-H）可用作以下反应的还原剂：
- 采用钴催化剂对酯改性的端羟基聚丁二烯（HTPB）进行加氢。
- 以三苯基四氟硼酸碳为催化剂通过吡喃己糖苷的4,6-苯亚甲基乙缩醛的区域选择性开环反应合成伯6-OH醇
- 酯转化为醇。
用于Pd催化的仲烷基溴的还原脱溴过程。过苄基化呋喃糖苷的O-脱苄基和开环。方便从 ZrCp2Cl2 和DIBAL-H原位生成 HZrCp2Cl。

A systematic investigation of the reductive ring-expansion reaction of cyclic ketoximes fused to aromatic rings with diisobutylaluminum hydride (DIBALH) is described. This reaction regioselectively afforded a variety of five- to eight-membered bicyclic heterocycles or tricyclic heterocycles containing nitrogen neighboring an
