Phenols reactions with 1,1-difluorodichloroethene, 1,2-di(fluorochloro) ethene, and trifluorochloroethene
Phenols containing in the para-position of the benzene ring substituents of various electronic character add to 1,1-difluorodichloroethene in acetone in the presence of potassium hydroxide. A similar reaction with 1,2-di(fluorochloro)ethene occurs only in
