Reduction of Esters With DIBAL-H

Professor Dave explains the use of various oxidizing and reducing agents, focusing on diisobutylaluminum hydride. This agent can reduce esters to aldehydes without going to alcohols, unlike lithium aluminum hydride. The video details the reduction mechanism, highlighting the role of aluminum as a Lewis acid. It also covers other applications of diisobutylaluminum hydride, such as reducing nitriles and lactones.
