Chapter 23, Problem 23.28P
Interpretation Introduction

Interpretation: The alkyl halides needed to prepare each ketone using the acetoacetic ester synthesis are to be predicted.

Concept introduction: The α hydrogen attached to the β- ketoester is acidic in nature and the hydrolysis and decarboxylation of the product obtained by substitution reaction of enolate ion with alkyl halide gives ketone. The ketone comprises of two components the alkyl group of alkyl halide and the β- keto ester.

(EXM 2, PRBLM 3) Here is this problem, can you explain it to me and show how its done. Thank you I need to see the work for like prbl solving.
can someone draw out the reaction mechanism for this reaction showing all bonds, intermediates and side products Comment on the general features of the 1H-NMR spectrum of isoamyl ester provided below
What would be the best choices for the missing reagents 1 and 3 in this synthesis? 1. PPh3 3 2. n-BuLi • Draw the missing reagents in the drawing area below. You can draw them in any arrangement you like. • Do not draw the missing reagent 2. If you draw 1 correctly, we'll know what it is. • Note: if one of your reagents needs to contain a halogen, use bromine. Click and drag to start drawing a structure.
