WebMar 31, 2024 · So, the rate of formation of H X − is very high from L i A l H X 4, which makes it stronger reducing agent. On the other hand, Di-isobutyl Aluminium Hydride is a pure covalent compound. It is difficult for it to donate reducing H X −, and after donation also, it can't get any extra stabilisation. Thus, eventually, it becomes weaker reducing ... http://www.commonorganicchemistry.com/Common_Reagents/Diisobutylaluminum_Hydride/Diisobutylaluminum_Hydride.htm
