Acetone → 4-Ethynylphenol

Participants

Reaction Steps

50.0 g of the resin synthesized in Reference Example 13 was dissolved in 500 ml of acetone. After adding 9.4 g of potassium carbonate, 1.9 g of potassium iodide and 8.5 g of tert-butylchloroacetate, the solution obtained was refluxed for 10 hours. Thereafter, same post-treatment as those in Reference Example 15 was repeated to obtain poly(p-vinylphenol), wherein 12% of the hydroxyl groups were ethyletherified and 14% of the hydroxyl groups were tert-butoxycarbonylmethyletherified. The weight average molecular weight of this resin is 15,000 and its molecular weight distribution is 1.28.
