  • Process for the condensation of compounds having silicon bonded hydroxy or alkoxy groups
    Patent number: 6753438
    Abstract: The specification describes preparation of materials comprising selected boron anions and processes using them as catalysts for condensation reaction of compounds having silicon-bonded hydroxy or alkoxy groups. Preferred anion compounds comprise borates incorporating quadri-substituted boron in which the substituents include highly halogenated hydrocarbon groups for example pentafluorinated phenyl groups or bis (trifluoromethyl) phenyl groups. Preferred anions are {B(C6F5)4}− and {B(C6(CF3)2H3)4}−.
