Abstract
Phenols are 2,6-divinylated by treatment with ethyne at 100 degrees C in chlorobenzene in the presence of SnCl4-Bu3N, the divinylation occur ring predominantly to exclusively with phenol, alkylphenols and alkoxy phenols; an appropriate amount of the tin reagent and the correct reac tion temperature are essential for the divinylation.
