WebAldehydes can be formed from esters using a strong reducing agent called Diisobutylaluminum hydride (abbreviated as DIBAH or DIBAL): This reaction is known as a reduction reaction. The ester molecule is cleaved at the “ether” oxygen, resulting in the formation of an aldehyde. If the starting ester is part of a ring, the ring will be ...

Ester Reactions: Ester Reduction to form Aldehydes using DIBAH

WebAnswer: LiAlH4, NaBH4 and DiBAL-H all act as reducing agents and all of them reduce by providing hydride ion(not exactly if we think in context of molecular orbitals but can be effectively visualised as supplying hydride ions) to the reactants. One major difference between these reagents are tha...
