4-Vinylphenol → 4-Ethynylphenol

Participants

Reaction Steps

29.1 g of the thus-obtained p-vinylphenol fraction as a polymerization raw material was placed in a 300-ml flask together with 24.5 g of acetonitrile. Thereto was dropwise added 0.8 ml of an acetonitrile solution of 2% of a boron trifluoride-diethyl ether complex with stirring and with the flask being cooled. A polymerization reaction as conducted in the same manner as in Example 1, and the reaction mixture was treated in the same manner as in Example 1 to obtain 8.8 g of a white poly(p-vinylphenol).
