應用
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。

The reaction of DIBALH with bis(heteroannulated)-pyranosides containing the perhydrofuro[2,3-b]pyran moiety is described. The hydride attack at the anomeric carbon (C-9a) resulted in the exclusive tetrahydrofuran ring opening. The selectivity of this reaction has been evaluated as other benzylidene acetals built
