Cyclohexa$-1,4-$diene

Vedclass · Answer

(B) $1$. The starting material is cyclohexane$-1,4-$diol. When treated with $2 	ext{ moles}$ of acetyl chloride in the presence of pyridine,it undergoes esterification to form cyclohexane$-1,4-$diyl diacetate,which is product $(A)$.$2$. Product $(A)$ undergoes thermal decomposition (pyrolysis of ester),which is a $syn$-elimination reaction.$3$. In this reaction,the acetate groups are eliminated as acetic acid $(CH_3CO_2H)$,leading to the formation of double bonds in the ring.$4$. Since the acetate groups are at the $1$ and $4$ positions,the elimination results in the formation of cyclohexa$-1,4-$diene as the major product $(B)$.

Product $(B)$ of the given reaction is:
