Fluorination of chlorophenyldisilanes with ZnF2 yields the corresponding fluorophenyldisilanes, if silver powder is used as a catalyst. 1,2-Difluorotetraphenyldisilane is synthesized by UV irradiation of bis-(fluorodiphenylsilyl)mercury, the first known fluorosilylmercury compound. All the eight possible fluorophenyldisilanes, unknown up to now, are characterized by spectroscopic methods.
