$2-$methylenecyclohexanone

Vedclass · Answer

(D) $1$. The first step is the oxidation of cyclohexanol using $PCC$ (Pyridinium chlorochromate),which is a mild oxidizing agent that converts secondary alcohols into ketones. Thus,$(A)$ is cyclohexanone.$2$. The second step is an aldol-type condensation reaction between cyclohexanone $(A)$ and formaldehyde $(H-CHO)$ in the presence of dilute $KOH$ and heat. This is a crossed-aldol condensation followed by dehydration.$3$. The $\alpha$-carbon of cyclohexanone attacks the carbonyl carbon of formaldehyde to form a $\beta$-hydroxy ketone intermediate,which subsequently undergoes dehydration (elimination of water) under heating conditions to form the $\alpha,\beta$-unsaturated product.$4$. The final product $(B)$ is $2$-methylenecyclohexanone.

In the given reaction sequence,identify the structure of $(B)$:
Cyclohexanol $\xrightarrow{PCC}$ $(A)$ $\xrightarrow{H-CHO, \text{dil. } KOH, \Delta}$ $(B)$
