Fluorinated monophenols and diphenols and method for their preparation

摘要

Phenol reactants and fluorinated aldehydes or fluorinated ketones are reacted in the presence of organic sulfonic acid catalysts to yield fluorinated monophenols and fluorinated diphenols. Fluorinated monophenols can be isolated and reacted with additional phenol reactant in the presence of organic sulfonic acid catalysts to yield asymmetrical, as well as symmetrical, fluorinated diphenols. A preferred organic sulfonic acid catalyst is methanesulfonic acid. The novel fluorinated monophenols have a hydroxy group and a fluorinated aryl radical or fluorinated alkyl radical substituted upon the benzylic carbon atom. The novel fluorinated diphenols have at least one fluorinated aryl radical or fluorinated alkyl radical substituted upon the methylene carbon atom of the bisphenol.
