Vedclass · Answer

(B) $1$. $DIBAL-H$ (Diisobutylaluminium hydride) is a selective reducing agent.$2$. When an ester $(R - CO - O - R')$ is treated with $DIBAL-H$ at low temperature followed by acidic workup $(H_3O^+)$, it is reduced to an aldehyde $(R - CHO)$ and an alcohol $(R'OH)$.$3$. The reaction stops at the aldehyde stage because the tetrahedral intermediate formed is stable at low temperatures and does not undergo further reduction to the primary alcohol.$4$. Therefore, the main organic product containing the carbonyl group is $R - CHO$.

Identify the main product of the following reaction: $R - CO - O - R' \xrightarrow[H_3O^+]{DIBAL-H} \text{Product}$
