Chapter 22, Problem 22.83AP
Interpretation Introduction

Interpretation:

The structure of the intermediate A, dimedone and curved arrow mechanism for compound B formation are to be stated.

Concept introduction:

In Claisen condensation reaction two esters or one ester and a carbonyl compound react together to form β ketoester and β-diketone compound in the presence of a base. Michael addition reaction is a nucleophilic addition reaction of an anion to α,β-unsaturated carbonyl compound and results in the formation of conjugate addition product. When ester undergoes basic hydrolysis, it results in the formation of carboxylate salt and an alcohol which is the reversible step of ester formation.

Part II. two unbranched ketone have molecular formulla (C8H100). El-ms showed that both of them have a molecular ion peak at m/2 =128. However ketone (A) has a fragment peak at m/2 = 99 and 72 while ketone (B) snowed a fragment peak at m/2 = 113 and 58. 9) Propose the most plausible structures for both ketones b) Explain how you arrived at your conclusion by drawing the Structures of the distinguishing fragments for each ketone, including their fragmentation mechanisms.
