The two structures for the assignment are above and
the task is:
1. Perform a retrosynthetic analysis on the two target
molecules assigned to you. In each case the organic
starting material (what you have to work backwards toward) depends
upon the target. For the structure given above (structure on left),
the starting material is either malonic ester or acetoacetic ester
and any halide. For the structure given above (structure on right),
the starting material is any...

Page 1 Synthesis using Carbonyl O-Substitution Chemistry Preamble This experiment involves the synthesis of target molecules using a-substitution chemistry. You are assigned two target molecules, one of which is best synthesized by an alkylation approach, while the other is best synthesized by an addition or condensation approach. You must do the following: 1. Perform a retrosynthetic analysis on the two target molecules assigned to you. In each case the organic starting material (what you have to work backwards toward) depends...

1. Compound X has a solubility in toluene of 18 mg per 100 mL at 20 °C, and a solubility of 0.64 g per 100 mL at 70 °C. You are given a sample of 0.48 g of compound X which is contaminated with 25 mg of compound Y. A. If compound Y is always soluble in toluene, describe in detail how you could separate Y from X. Would x now be pure? B. If compound Y has approximately the same values of...
