The observation, when the unsymmetrical ketone , 2-methylcyclohexenone is converted into an enamine the sole product is the one with the double bond opposite to the methyl substituted carbon while the other possible enamine with methyl on the carbon in double bond is not formed, is to be explained. Concept introduction: The enamine obtained from an unsymmetrical ketone will be stable only if it is free from steric strain. A strained unsymmetrical ketone will be unstable. To explain: The observation, when the unsymmetrical ketone, 2-methylcyclohexenone is converted into an enamine the sole product is the one with the double bond opposite to the methyl substituted carbon while the other possible enamine with methyl on the carbon in double bond is not formed.

Question

Draw the stepwise mechanism for the reactions

Answer 1

Question

Definition Definition Organic compounds that have a carbonyl group, C = O, as their functional group. The carbonyl group in ketones is placed somewhere in the middle of the molecular structure, which means, the C=O is attached to two alkyl groups or benzene rings. Just like all other homologous series, the naming of ketones is done using a common suffix “-one”. The general molecular formula is C n H 2n O. Functional group of a ketone
