Chapter 26, Problem 26.52P
Interpretation Introduction

Interpretation:

Poly(ethylene terephthalate) is a linear polyester that can be synthesized from the condensation polymerization between terephthalic acid and ethylene glycol. The alcohol we would react with terephthalic acid to produce a branched polyester is to be found. A portion of the resulting polymer that shows a main chain and one branching point is to be drawn.

Concept introduction:

Step-growth polymerizations are referred to as condensation polymerization, because a small molecule (in this case, water) is formed as a product. Step-growth polymerization occurs when molecules throughout a mixture join with any other molecule that has an appropriate functional group available to react, whether it is a monomer unit or another polymer molecule. Many nucleophilic addition–elimination reactions can be used to make step-growth polymers. The condensation polymerization between terephthalic acid and ethylene glycol is also called as the Fischer esterification:

Organic Chemistry: Principles And Mechanisms, Chapter 26, Problem 26.52P

The linear alcohol, ethylene glycol, forms a linear polymer. Therefore, in order to form a branched polymer, a branched alcohol is required. Branching can occur during polymerization when a monomer has multiple reactive sites. Such a branched alcohol is ethane-1, 1, 2-triol which can be used here to produce branched polyester.

Identify the missing starting materials/ reagents/ products in the following reactions. Show the stereochemistry clearly in the structures, if any. If there is a major product, draw the structures of the major product with stereochemistry clearly indicated where applicable. Show only the diastereomers (you do not have to draw the pairs of enantiomers). If you believe that multiple products are formed in approximately equal amounts (hence neither is the major product), draw the structures of the products, and show the detailed mechanism of these reactions to justify the formation of the multiple products. If you believe no product is formed, explain why briefly. (6 mark for each, except f and g, which are 10 mark each)
3. What starting material would you use to synthesize 3-hydroxypentanoic acid using a NaBH4 reduction?
