Hypothesis
The study aimed to activate the triple bond of 4,4'-bis(prop-2-ynyloxy)biphenyl for polymerization using a cuprous iodide/iodine catalytic system.
Conclusion
The attempt to polymerize the compound resulted in the formation of an iodinated product instead.
Supporting Evidence
- Iodine adds across both triple bonds of the compound.
- The aromatic rings in the molecule are twisted by 37.8 degrees.
Takeaway
The researchers tried to make a new plastic from a chemical but ended up making a different chemical with iodine instead.
Methodology
The compound was synthesized by dissolving potassium carbonate and biphenyl-4,4'-diol in ethanol, followed by the addition of propargyl bromide and treatment with a cuprous iodide/iodine solution.
