Abstract

Aromatic ethers or polyethers are produced by reacting aromatic fluorine compounds, in which one or more fluorine substituents are attached to an aromatic nucleus, with trialkyl silyl derivatives of phenols, in which one or more trialkyl silyl groups are attached to the residue of a mono- or polyphenol, or by reacting trialkyl silyl derivatives of fluorophenols with elimination of trialkylfluorosilane.
